| Popis: | International audience; 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. |
