Four new mononuclear complexes, [Ni(L1)(NCS)2] (1), [Ni(L2)(NCS)2] (2), [Co(L1)(N3)2]ClO4 (3), and [Co(L2)(N3)2]ClO4 (4), where L1 and L2 are N,N'-bis[(pyridin-2-yl)methylidene]butane-1,4-diamine and N,N'-bis[(pyridin-2-yl)benzylidene]butane-1,4-diamine, respectively, have been prepared. The syntheses have been achieved by reaction of the respective metal perchlorate with the tetradentate Schiff bases, L1 and L2, in presence of thiocyanate (for 1 and 2) or azide (for 3 and 4). The complexes have been characterized by microanalytical, spectroscopic, single crystal X-ray diffraction and other physicochemical studies. Structural studies reveal that 1-4 are distorted octahedral geometries. The antibacterial activity of all the complexes and their constituent Schiff bases have been tested against Gram-positive and Gram-negative bacteria.
