A few mono and bimetallic trinuclear metal complexes of the type [MCuM(BAHBD)2X2 (H2O)4 ], where M = CuII, NiII, CoII; X = Cl, Br, NO3 and BAHBD = bis(N2 ,N´-acetylacetonehydrazonato)-N1 ,N1´-benzil dihydrazone have been isolated in a stepwise reaction from the precursor copper bis(benzil dihydrazone) complex. These have been characterized on the basis of elemental analysis, spectral and magnetic properties, conductivity measurements and thermal analyses. The ligand as well as the metal complexes exhibited good antimicrobial activities against the pathogenic fungus Aspergillus niger, Helminthosporium oryzae and Fusarium oxysporium.
