Abstract
Coordination compound [Ni(L)3]Cl2 · 2H2O (L is benzohydrazide) has been synthesized and studied by IR spectroscopy and X-ray diffraction analysis. According to X-ray diffraction, one of the Cl– ions is disordered over two nonequivalent positions. The crystals are monoclinic, a = 15.423(3) Å, b = 9.697(2) Å, c = 18.893(4) Å, ß = 105.99(3)°, space group P21/c, Z = 4. The structural units of the crystal are complex cations [Ni(L)3]2+, in which ligands L are coordinated to the central atom bidentately chelating the metal atoms through the O and N atoms of the hydrazide moiety (Ni–O 2.036(4), 2.051(5), 2.047(5); Ni–N 2.095(5), 2.089(6), 2.097(6) Å). The structural units of the crystal are joined together by cation–anion electrostatic interactions and hydrogen bonds, which involve both H2O molecules, both Cl– anions and the N atoms of chelate rings of the complex cation.
