Bis(μ-chloroacetato-κ2 O:O′)bis(chloro­acetato-κO)di-μ3-oxido-tetrakis[dibenzyl­tin(IV)]

The title tetra­nuclear complex mol­ecule, [Sn4(C7H7)8(C2H2ClO2)4O2], has crystallographically imposed inversion symmetry. Each Sn atom has a distorted trigonal–bipyramidal geometry, with the equatorial plane formed by an oxido O atom and two C atoms of two benzyl anions. The configuration of the complex is stabilized by a pair of C—H⋯O hydrogen bonds. In the crystal, complex mol­ecules are linked into zigzag chains along [110] by C—H⋯O hydrogen bonds

catena-Poly[[[pyridinecopper(II)]-(μ-2-oxidonaphthalene-1-carbaldehyde pico­linoylhydrazonato)-[pyridinecopper(II)]-μ-sulfato] diethyl ether hemisolvate]

The title compound, {[Cu2(C17H11N3O)(SO4)(C5H5N)2]·0.5C4H10O}n, was syn­thesized by the reaction of 2-hydr­oxy-1-naphthyl­aldehyde-2-pyridine­carboxyl­hydrazone with copper sulfonate. A one-dimensional polymer was obtained via self-assembly. Each Cu ion is located in a distorted square-pyramidal coordination environment, with one Cu ion coordinated by two N and three O atoms, while the other links to two O and three N atoms. In the crystal, weak inter­molecular C—H⋯O inter­actions connect the chains into a two-dimensional network

Chlorido(2-chloro­nicotinato)triphenyl­anti­mony(V)

In the title complex, [Sb(C6H5)3(C6H3ClNO2)Cl], the Sb center has a close to ideal trigonal-bipyramidal geometry, with the phenyl ligands in equatorial positions and the chloride and a carboxyl­ate O atom in axial positions. Weak C—H⋯O contacts generate dimeric units via crystallographic inversion centres

3-Eth­oxy-2-(1,3-thia­zol-2-yl)isoindolin-1-one

In the title compound, C13H12N2O2S, the dihedral angles between the isoindolone ring system and the thia­zole ring and the eth­oxy group are 6.50 (11) and 89.0 (2)°, respectively

catena-Poly[[nickel(II)-μ3-1,1-dicyano­ethene-2,2-dithiol­ato-κ4 S,S′:N:N′-bis­[(15-crown-5)magnesium(II)]-μ3-1,1-dicyano­ethene-2,2-dithiol­ato-κ4 N:N′:S,S′] dichloride]

The reaction of MgCl2, NiCl2, and Na2(i-mnt) (i-mnt is 1,1-dicyano­thene-2,2-dithiol­ate) with 15-crown-5 (15-C-5) leads to an infinite chain polymer, {[NiMg2(C4N2S2)2(C10H20O5)2]Cl2}n or {[Mg(15-C-5)]2[Ni(i-mnt)2]Cl2}n, which consists of two [Mg(15-C-5)]2+ complex cations, one [Ni(i-mnt)2]2− complex anion and two Cl− ions per formula unit. In the [Ni(i-mnt)2]2− complex anion, Ni2+ is located on a crystallographic mirror plane with a slightly distorted square-planar coordination by four S atoms. In the [Mg(15-C-5)]2+ complex cations, the Mg and one O atom of the crown lie on mirror planes and the Mg atoms are in sevenfold coordination environments of five O atoms from the crown and two N atoms from two i-mnt anions. The bridging of the two complexes via the Mg—N bonds leads to the formation of one-dimensional chains along the a axis

Di-μ-hydroxido-bis­[aqua­trichlorido­tin(IV)] diethyl ether disolvate

The title compound, [Sn2Cl6(OH)2(H2O)2]·2C4H10O, consists of a centrosymmetric molecule and two additional solvent molecules and has an infinite two-dimensional network extending parallel to (101). The Sn atom is six-coordinate with a distorted octa­hedral geometry. Additional O—H⋯O hydrogen bonding leads to stabilization of the crystal structure

μ-3-Thienylmalonato-κ2 O 1:O 3-bis­[triphenyl­tin(IV)]

The title compound, [Sn2(C6H5)6(C7H4O4S)], contains two molecules with similar conformations in the asymmetric unit. In each mol­ecule, the Sn atoms adopt a distorted tetra­hedral geometry arising from three C atoms of three phenyl rings and one O atom from the bridging 3-thienylmalonato ligand. The mol­ecules lie about inversion centers with the ligands facing each other, with C⋯O distances of 3.417 (10) and 3.475 (10) Å

The title complex, [Mn(NCS)2(C13H19NO4)] {systematic name: [3,6,9,12-tetra­oxa-18-aza­bicyclo­[12.3.1]octa­cosa-14(18),15,17-triene-κ5 N,O,O′,O′′,O′′′]bis­(thio­cyanato-κN)manganese(I­I)}, was obtained by the reaction of MnCl2·4H2O and NaSCN with pyridino-15-crown-5. The Mn2+ center has a distorted penta­gonal bipyramidal coordination geometry, coordinated by four O atoms and one N atom of the pyridino-15-crown-5 mol­ecule, and by the N atoms of the two NCS− ligands

1,5-Bis(2-chloro­benzyl­idene)carbonohydrazide

In the title mol­ecule, C15H12Cl2N4O, the two benzene rings are inclined at a dihedral angle of 14.5 (2)°. In the crystal, inter­molecular N—H⋯O hydrogen bonds link mol­ecules into chains propagated in [001]

Tetra­kis(μ3-2-{[1,1-bis­(hydroxy­meth­yl)-2-oxidoeth­yl]imino­meth­yl}-6-methoxy­phenol­ato)tetra­nickel(II) tetra­hydrate

The title complex, [Ni4(C12H15NO4)4]·4H2O, has crystal­lographic fourfold inversion symmetry, with each NiII ion coordinated in a slightly distorted square-pyramidal coordination environment and forming an Ni4O4 cubane-like core. In the crystal structure, inter­molecular O—H⋯O hydrogen bonds connect complex and water mol­ecules to form a three-dimensional network. The O atom of one of the unique hydroxy­methyl groups is disordered over two sites, with the ratio of occupancies being approximately 0.79:0.21
