Abstract:
The ligand HL (HL= N-acetylpicoloylhydrazide, α-(C5H 4N)CONHNHCOCH3) and its nickel complex NiL 2·1.5H2O (C17.5H24N 6NiO6.5) have been synthesized. Crystal data: space group P21/c, a = 1.5393(1) nm, b = 0.80278(7) nm, c = 1.8245(1) nm, β = 105.985(3)°, V = 2.174(3) nm3, Z = 4, F(000) = 1004, R = 0.0503 for 2799 observed reflections [I≥2σ(I)]. The nickel atom in the complex is of irregular polyhedral N4O2 coordination. There is a one-dimensional chain structure through the intermolecular hydrogen bonds. The ν(C=O) and ν(C= N) bands display a shift to lower frequencies in IR spectra. There are π-π* transition and d-π* charge-transfer transition in electronic spectra.
