A coordination compound of nickel(II) benzoate with nicotinamide [Ni(C6H5COO)(2)(L)(2)(H2O)(2)] (I) (L is nicotinic acid amide) is synthesized and studied by IR spectroscopy. Its crystal structure is solved by X-ray crystallography. The crystals of compound I are monoclinic: a = 7.152 angstrom, b = 18.266 angstrom, c = 10.341 angstrom, beta = 109.24 degrees, V = 1275.4 angstrom(3), Z = 2, space group P2(1)/c. Structural units of a crystal of I are centrosymmetric octahedral complex molecules. The coordination environment of the Ni atom contains two O atoms (Ni-O(1) 2.066(2)angstrom) and two N atoms (Ni-N(1) 2.091(2) angstrom) of the monodentate-coordinated benzoate anions and nicotinamide molecules, respectively, as well as two O atoms of the H2O molecules (Ni-O(1w) 2.110(2)angstrom).
