metal-organic compounds
The mononuclear complex of the title compound [alternative IUPAC name: bis(acetato-O)bis(pyridine-2-carboxamide oxime-N,N')nickel(II)-ethanol (1/2)], [Ni(C2H3O2)2(C6H7N3O)2].2C2H5OH, crystallizes from ethanol as a disolvate. The coordination geometry at the Ni atom is distorted octahedral, with crystallographic twofold symmetry. The pyridine-2-carboxamide oxime ligands are coordinated to the metal through the N atoms of the pyridine ring and the oxime group. The acetate ligands are monodentate. The ethanol solvate molecule is linked to the non-coordinated O atoms of the acetate ligands via a hydrogen bond.
