Tris(1,2-diamino­ethane)­nickel(II) hexa­fluoridosilicate

The ionic title complex, [Ni(C2H8N2)3](SiF6), is built up of [Ni(en)3]2+ complex cations (en = 1,2-diamino­ethane) and hexa­fluoridosilicate anions. Single crystals of the title complex were isolated from an aqueous–ethano­lic Ni2+–en–SiF6 2− system. The Ni(II) and Si atoms are each located on a special position with site symmetry 3.2. The Ni(II) atom coordination sphere is octa­hedrally deformed, being coordinated by three chelating diamine ligands with an Ni—N distance of 2.1233 (18) Å. The crystal packing of the respective ions corresponds to the structure type of the hexa­gonal form of BN. Beside ionic forces, the packing is governed by N—H⋯F hydrogen bonds, which lead to the formation of hydro­phobic channels running along the 63 screw axis. The structure was refined as an inversion twin [0.49 (3): 0.51 (3)]

Di-μ-hydroxido-bis­[hemiaqua­(N,N,N′,N′-tetra­methyl­ethane-1,2-diamine)­copper(II)] bis­(tetra­fluoridoborate)

The title compound, [Cu2(OH)2(C6H16N2)2(H2O)](BF4)2, consists of dinuclear centrosymmetric [Cu2(OH)2(tmen)2(H2O)]2+ complex cations (tmen = N,N,N′,N′-tetra­methyl­ethane-1,2-diamine) and tetra­fluoridoborate anions. In the cation, the CuII atom shows a slightly distorted square-pyramidal coordination geometry provided by a pair of μ-OH− anions and by the N atoms of a chelate tmen ligand in the basal plane. The apical position is statistically occupied by the O atom of a half-occupancy water mol­ecule. The F atoms of the anion are disordered over three sets of sites with occupancies of 0.598 (9):0.269 (6):0.134 (8). The crystal packing is governed by ionic forces as well as by O—H⋯F hydrogen bonds

Economical Demands On Athletes From 8 To 18 Years In Czech Republic

Today’s world is increasingly more dealing with a constant problem of finance and financial aspects whether it is the functioning of a state, company, household, sport club or an individual. After the outbreak of the world and financial and economic crisis, economic decision-making gets more and more to the forefront and all of the economic subjects mentioned above will think twice before they invest their money in some effort. The same goes for sport itself. In the Czech Republic sport receives money from three sources – from the state, from the sports club and ultimately also from households themselves. The state contributes a certain percentage of the state budget to the development of Youth and sports in the country each year, however this number is far from covering all the expenses that are necessary to provide for the needs and functioning the sport. The second source are the club owners who attract sponsors and other entities which provide financial assistance. Money can be obtained from sponsorships, advertising, TV rights etc. However, not even this does not absolutely cover all the expenses that are associated with practicing a particular sport. Therefore, there is one last entity and these are households. In order for the sports clubs and individual sports to function properly, a part of the funds needs to be covered by households. Unfortunately, this percentage increases year after year. To support the children to practice the sport of their choice is extremely difficult both financially and sometimes even mentally. This article is focused on the financial aspect of athletes sport. The research was based on a survey in Prague city and Central Bohemian region. The questionnaire survey aimed to find out how big are the financial costs covered by the households in different age categories from 8 to 18 years. Individual values for all age categories were added to the total number that should reflect the total costs incurred in raising a child from an early age to senior age – the time when the sportsman usually starts earning money by practicing the sport. The research and paper was prepared within the project “Economy of sportsman in Czech Republic” funded by Internal grant agency at University of Economics, Prague.Today’s world is increasingly having to deal with the constant problem of finance and other financial aspects whether it is the functioning of a state, company, household, sport club or an individual.

catena-Poly[[bis­(N-ethyl­ethylene­di­amine-κ2 N,N′)copper(II)]-μ-cyanido-κ2 N:C-[dicyanido-κ2 C-palladium(II)]-μ-cyanido-κ2 C:N]

The title compound, [CuPd(CN)4(C4H12N2)2]n, consists of one-dimensional chains. The Cu and Pd atoms are both located on centers of symmetry in an alternating array of [Cu(N-Eten)2]2+ (N-Eten = N-ethyl­ethylenediamine) and [Pd(CN)4]2− units. The Pd—C distances of 1.991 (3) and 1.992 (3) Å are inter­mediate values compared with the analogous NiII and PtII complexes [Akitsu & Einaga (2007 ▶). Inorg. Chim. Acta, 360, 497–505]. Due to Jahn–Teller effects, the axial Cu—N bond distance of 2.548 (2) Å is noticeably longer than the equatorial distances [Cu—NH2 = 2.007 (2) and Cu—NHC2H5 = 2.050 (2) Å]. There are interchain hybrogen bonds, with N(—H)⋯N = 3.099(4) Å

The chain structure of [Ni(C4H2O4)(C12H8N2)(H2O)]n with different types of fumarate bridging

Using modified solvothermal conditions (longer cooling time), beside previously characterized dark-green crystals of [Ni(C4H2O4)(C12H8N2)] (main product), a few light-green crystals of the polymeric title compound, catena-poly[[aqua­(1,10-phenanthroline-κ2 N,N′)nickel(II)]-μ-fumarato-κ2 O:O′-[aqua­(1,10-phenanthroline-κ2 N,N′)nickel(II)]-μ-fumarato-κ4 O,O′:O′′,O′′′], [Ni(C4H2O4)(C12H8N2)(H2O)]n were isolated. Its crystal structure is made up from zigzag chains, propagating in [001], in which the Ni2+ ions are linked alternatively by μ2-fumarato and bis-chelating fumarato bridging ligands. The Ni2+ ion is coordinated in a deformed octa­hedral geometry by one chelating 1,10-phenanthroline ligand, one aqua ligand in a cis position with regard to both N-donor atoms and by two different fumarato ligands, each residing with its central C=C bond on an inversion centre, occupying the remaining coordination sites in a fac fashion. The chains thus formed are linked by O—H⋯O hydrogen bonds and π–π inter­actions between the aromatic rings of the phenanthroline ligands with a shortest ring centroid separation of 3.4787 (10) Å

Tris(propane-1,2-diamine-κ2 N,N′)nickel(II) tetra­cyanidonickelate(II)

The title compound, [Ni(C3H10N2)3][Ni(CN)4], is built up of [Ni(pn)3]2+ cations (pn is 1,2-diamino­propane) and [Ni(CN)4]2− anions. Both NiII atoms in the cation and the anion lie on a mirror plane. The respective ions inter­act through Coulombic forces and through a complex network of hydrogen bonds. Extended disorder associated with the cation has been resolved. The occupancies of the respective disordered positions are 0.4:0.4:0.2

Syntheses, crystal structures and magnetic properties of complexes based on [Ni(L-L)3]2+ complex cations with dimethylderivatives of 2, 2'-bipyridine and TCNQ

From the aqueous-methanolic systems Ni(NO3)2 – LiTCNQ – 5, 5'-dmbpy and Ni(NO3)2 – LiTCNQ – 4, 4'-dmbpy three novel complexes [Ni(5, 5'-dmbpy)3](TCNQ)2 (1), [Ni(4, 4'-dmbpy)3](TCNQ)2 (2) and [Ni(4, 4'-dmbpy)3]2(TCNQ-TCNQ)(TCNQ)2·0.60H2O (3), were isolated in single crystal form. The new compounds were identified using chemical analyses and IR spectroscopy. Single crystal studies of all samples corroborated their compositions and have shown that their ionic structures contain the complex cations [Ni(5, 5'-dmbpy)]2+ (1) or [Ni(4, 4'-dmbpy)]2+ (2 and 3). The anionic parts of the respective crystal structures 1–3 are formed by TCNQ·- anion-radicals and in 3 also by a s-dimerized dianion (TCNQ-TCNQ)2- with a C-C distance of 1.663(5) Å. The supramolecular structures are governed by weak hydrogen bonding interactions. The variable-temperature (2–300 K) magnetic studies of 1 and 3 confirmed the presence of magnetically active Ni(II) atoms with S = 1 and TCNQ·- anion-radicals with S = 1/2 while the (TCNQ-TCNQ)2- dianion is magnetically silent. The magnetic behavior was described by a complex magnetic model assuming strong antiferromagnetic interactions between some TCNQ·- anion-radicals
