Synthesis, Structures, and Antimicrobial Studies of Copper(II) and Zinc(II) Complexes with Schiff Bases Derived from 2-Acetylpyridine and Propane-1,3-diamine

A new dicyanamido-bridged polymeric copper(II) complex, [Cu(L1)(DCM)] n ·nBF4 (1), and a new thiocyanato-coordinated mononuclear zinc(II) complex, [Zn(L2)(NCS]·BF4 (2) (L1 = N-(1-pyridin-2-ylethylidene)propane-1,3-diamine, L2 = N,N′-bis(1-pyridin-2-ylethylidene)propane-1,3-diamine), have been prepared and characterized by elemental analysis and infrared spectroscopy. The structures of the complexes have been determined by X-ray crystallography. The coordination geometry around the Cu atom in (1) and Zn atom in (2) are distorted square pyramid. The antimicrobial activity of the complexes was studied.
