Poly[[diaquacaesium(I)]bis(mu(3)-3-carboxy-pyrazine-2-carboxylato)]

WOS: 000248149900019The asymmetric unit of the title compound, [Cs(C6H3N2O4)(2)(H2O)(2)](n), contains one Cs-I cation on an inversion centre, one 3-carboxypyrazine-2-carboxylate anion and one water molecule. In the crystal structure, each anion is linked to three cations, while each cation is surrounded by six of the anions. In addition, each cation is coordinated by two water O atoms, raising the coordination number to ten. In the crystal structure, intermolecular O - H center dot center dot center dot O and O - H center dot center dot center dot N hydrogen bonds contribute to the stabilization of the structure

Coupling of pentacarbonyl[(cyclopropyl)methoxymethylene]molybdenum complex with ferrocenylalkynes: Synthesis of ferrocenyl-substituted cycloheptadienones and cycloheptenediones

Pentacarbonyl[(cyclopropyl)methoxymethylene ]molybdenum complex reacts with ferrocenyl alkynes to afford ferrocenyl-substituted 2,4-cycloheptadienones as major products, accompanied by varying amounts of 2-cycloheptene-1,4-diones and/or 2-cyclobutenones. 2-Cycloheptene-1,4-diones are secondary reaction products and result from initially formed 2,4-cycloheptadienones via hydrolysis. In one reaction, a hydroxy-substituted 2,4-cycloheptadienone derivative was isolated, which was not observed previously from similar reactions

Synthesis and crystal structure of square-planar and mixed ligand octahedral nickel(II) O,O '-dicyclopentyl dithiophosphate complexes

TAS, MURAT/0000-0002-2879-6501WOS: 000252610900005Ammonium O,O'-dicyclopentylphosphorodithioate (dcpdtp) has been synthesized from phosphorus pentasulphide and cyclopentanol in the presence of ammonia gas. Its complexes, I=[Ni(dcpdtp)(2)] and II= [Ni(bP)(2)(dcpdtp)(2)] (bp=4-benzylpiperidine), have been synthesized and their structures characterized by using UV-vis, IR spectroscopy, magnetic susceptibility measurements and X-ray single crystal structural analysis. The complexes crystallize in the triclinic system (space groups P (1) over tilde) and exhibit a slightly distorted square planar [NiS4] and trans-octahedral [NiS4N2] geometry for the complexes I and II, respectively

Bis(phenanthridinium) hexachloridoplatinate(IV) dimethyl sulfoxide disolvate

The asymmetric unit of the title compound, (C(13)H(10)N)(2)-[ PtCl(6)]center dot 2C(2)H(6)OS, contains one independent protonated phenanthridinium cation, half of a centrosymmetric [PtCl(6)](2-) anion and one dimethyl sulfoxide solvent molecule. Intramolecular N-H center dot center dot center dot O and intermolecular C-H center dot center dot center dot Cl hydrogen-bonding interactions seem to be effective in the stabilization of the structure
