Abstract: Four new nickel(II), zinc(II) and manganese(III) complexes, [NiL] (1), [Zn3L2(OAc)2] (2), [ZnL(CH3OH)] (3) and [MnClL(DMF)] (4), derived from the bis-Schiff base N,N'-bis(4-bromosalicylidene)propane-1,2-diamine (H2L) have been prepared and characterized by spectroscopy methods, as well as single crystal X-ray determination. The Ni atom in the mononuclear nickel complex 1 is in square planar coordination. The outer and inner Zn atoms in the trinuclear zinc complex 2 are in square planar and octahedral coordination, respectively. The Zn atom in the mononuclear zinc complex 3 is in square pyramidal coordination. The Mn atom in the mononuclear manganese complex 4 is in octahedral coordination. Antibacterial activity of the complexes has been assayed on the bacteria Staphylococcus aureus and Escherichia coli, and the yeast Candida parapsilosis.
