Nickel(II) complex of [NiL2](ClO4)2, where L is an unsymmetrical tridentate ligand of 2–(2–aminoethyl)imino–3–butanone oximehas been synthesized by a template condensation reaction. The complex was characterized on the basis of microanalytical, spectroscopic, and other physicochemical properties. X–ray diffraction study of the complex reveals nickel(II) center in a distorted octahedral environment through two amine nitrogen donors, two imine donors,and two nitrogen atoms of the oxime moieties of the ligand. The antibacterial activity of the complex has been tested against Gram(+) and Gram(–) bacteria. The results of the antibacterial screening indicated that the complex is effective against bacterial growth retardation activity to some extent and its effectiveness is higher forGram(+) bacteria.

A binuclear macrocyclic ligand containing dissimilar N(amine)2O2 and N(imine)2O2 coordination sites sharing two phenolic oxygen atoms, was prepared by cyclic condensation of dialdehyde precursor L1H2 with 1,3–diaminopropane. The ligand includes two propionitrile pendant arms on the amine nitrogen atoms. The homobimetallic complex [ZnL2Zn(OAc)]PF6 was synthesized by one step procedure. Heterobimetallic complexes [ZnL2M(OAc)]PF6 that M= Cu(II) and Ni(II), were prepared by a trans–metallation reaction. The prepared complexes were characterized on the basis of molar conductance measurement, elemental analysis, IR, NMR and UV–Vis spectroscopy techniques. Characterization results showed that the nitrogen atoms of propionitrile pendant arms are not involved in the coordination to the metal center and also the two metal ions are bridged by two phenolic oxygen atoms and an acetate group.
