Six zinc(II) complexes have been synthesized from two designed Mannich-base ligands which consist of three dinuclear complex [Zn2(L(1))2X2] (1-3) and three mononuclear complex [ZnH(L(2))X2] (4-6), respectively, where X = Cl(-) (1,4), Br(-) (2,5), I(-) (3,6), as reported earlier by us (Sanyal et al.,
