Abstract
The structure of the title compound, [Co2(C7H7N2O2)4(H2O)2]·2H2O, consists of a centrosymmetric binuclear [Co2(4-Apha)4(H2O)2] complex molecule (4-AphaH = 4-aminophenylhydroxamic acid), and two solvent water molecules. Each CoII cation is six coordinate, binding five oxygen atoms from three 4-Apha− ligands and a water molecule in a slightly distorted octahedral geometry. Two of the 4-Apha− ligands bridge two neighbouring CoII ions to form the binuclear complex. A three-dimensional network structure is generated by O—H...O, N—H...O, and N—H...N hydrogen bonds.
