Abstract
Abstract The 2-methylimidazole complexes of Co(II), Ni(II), Cu(II) and Zn(II) orotates, mer -[Co(HOr)(H 2 O) 2 (2-meim) 2 ] ( 1 ), mer -[Ni(HOr)(H 2 O) 2 (2-meim) 2 ] ( 2 ), [Cu(HOr)(H 2 O) 2 (2-meim)] ( 3 ) and [Zn(HOr)(H 2 O) 2 (2-meim)] ( 4 ), were synthesized and characterized by elemental analysis, spectral (UV–Vis and FT-IR) methods, thermal analysis (TG, DTG and DTA), magnetic susceptibility, antimicrobial activity studies and single crystal X-ray diffraction technique. The complexes 1 and 2 have distorted octahedral geometries with two monodentate 2-methylimidazole and one bidentate orotate and two aqua ligands. The complexes 3 and 4 have distorted square pyramidal and trigonal bipyramidal geometry, respectively, with one 2-methylimidazole, bidentate orotate and aqua ligands. The orotate coordinated to the metal(II) ions through deprotonated nitrogen atom of pyrimidine ring and oxygen atom of carboxylate group as a bidentate ligand. The antimicrobial activities of 1 and 4 were found to be more active gram (+) than gram (−) and 4 could be use for treatment Staphylococcus aureus .
