چکیده انگلیسی
The new complexes [Mn(ptt)2(en)2] (1), [Ni(ptt)2(en)2] (2), [Cu(ptt)2(en)2] (3), [Zn(ptt)2(en)] (4), [Hg(ptt)2(en)] (5) [Cd(ptt)2(en)2] (6), [Cd2(μ-ptt)2(ptt)2(bpy)2] (7) and [Co(phen)3](ptt)2 (8), obtained from 1-phenyl-1H-tetrazole-5-thiol (Hptt), have been described. The complexes have been characterized by elemental analyses, IR, UV-Vis and single crystal X-ray data. The ligand is covalently bonded through the deprotonated tetrazole ring nitrogen atom in complexes 1-4 and via the thiolato sulfur atom in complexes 5 and 6, in which the ligand acts as uninegative monodentate. Complex 7 is dimeric via thiolato bridging, in which two terminal ligands act as uninegative monodentate while the other two act as uninegative bridging bidentate. Complex 8 is ionic, where the cationic part, [Co(phen)3]2+, is held by two tetrazole anions through hydrogen bonding. The bioefficacy of complexes 1-4 and 8 has been examined against the growth of bacteria in vitro to evaluate their anti-microbial potential.
