Abstract

Three mononuclear copper(II) complexes, viz. [CuL1] (1), [CuL2] (2), [CuL3] (3), and one nickel(II) complex, viz.[NiL3] (4) where H2L1 = 3,3′-{(methylazanediyl)bis[(propane-3,1-diyl)azanylylidenemethanylylidene]}bis(4-bromophenol), H2L2 = 2,2′-[1,2-phenylenebis(azanylylidenemethanylylidene)]bis(4-bromophenol) and H2L3 = 3,3′-{(methylazanediyl)bis[(propane-3,1-diyl)azanylylidenemethanylylidene]}bis(4,6-dibromophenol), have been prepared. The syntheses have been carried out by the reaction of copper perchlorate (for 1–3) or nickel perchlorate (for 4) with the corresponding Schiff base in the molar ratio of 1:1. The complexes have been characterized by several physicochemical techniques including single-crystal X-ray diffraction. Structural studies reveal that the complexes 1, 3 and 4 adopt distorted trigonal bipyramidal structures, while 2 adopts a distorted square planar geometry. The antibacterial activity of the complexes and the constituent Schiff bases has been tested against two Gram(+) and two Gram(−) bacteria.
