dc.description.abstract | Benzoylhydrazine and isonitrosoacetone react in ethanol with cobalt, nickel, and copper halides and acetates to give the coordination compounds MX2(HL)·nH2O, MX2(HL) 2·nH2O, and ML2·nH2O [M = Co, Ni, Cu; X = Cl, Br; HL = C6H5C(O)NHNC(CH 3)CHNOH; n = 1-4]. The same reactions performed in the presence of sodium acetate and pyridine (pH 7-8) yield the complexes MLCl·nH 2O and MPy2LCl·nH2O (n = 1-4). All the complexes have a pseudooctahedral coordination geometry. The hydrazone HL behaves as a tridentate O,N,N-donor ligand. Thermolysis of the substances involves dehydration (70-90°C), deaquation (155-170°C) or deamination (175-195°C), and complete thermal decomposition (285-360°C). | en |
