Benzoylhydrazones of 5-nitro- (H2L1), 3-nitro- (H2L2), 5-chloro- (H2L3), 5-bromo- (H2L4), and 3,5-dibromosalicylaldehydes (H 2L5) react in ethanol with copper acetate to form complexes CuL1-5. In the presence of amines (A = C5H 5N, 3-CH3C5H4N), the above reactions give complexes CuL1-5A·nH2O (n = 0, 1). When cuprous bromide or nitrate and benzoylhydrazone H2L3 were used as starting materials, complexes Cu(HL3)X (X = Br-, NO3-) were isolated. The resulting complexes all are polynuclear structures in which azomethines H2L1-5 behave as tridentate O,N,O-ligands. Thermolysis of the complexes involves the stages of dehydration (70-90°C), deaquation (120-150°C) or deamination (150-180°C), and complete thermal decomposition (350-500°C). |
