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.

Synthesis, Structures, and Antimicrobial Studies of Cobalt(III) Complexes with Tridentate Schiff Bases

Two new cobalt(III) complexes, [Co2(L1)2(AEN)(N3)] (1) and [Co(L2)(PEA)(N3)] (2) (L1 = 2-[1-(2-hydroxyethylimino) ethyl]phenolate, L2 = 2-[1-(2-phenylaminoethylimino)ethyl] phenolate, AEN = 2-aminoethanolate, PEA = N-phenylethane-1,2-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 cobalt atoms in both complexes is distorted octahedral with one tridentate Schiff base ligand, one bidentate ligand, and one monodentate azide ligand. The antimicrobial activity of the complexes was studied.
