Synthesis, Characterization, and Antibacterial Studies of Some Metal Complexes of Dialkyl Thiourea: The X-Ray Single Crystal Structure of [CoCl2(detu)2]

Co(II), Cu(II), and Zn(II) complexes of diethylthiourea and dimethylthiourea have been synthesized and characterized by elemental analysis, conductivity, magnetic susceptibility measurements, and FTIR UV-vis spectroscopy. The single-crystal X-ray structure of the Co(II) complex of diethylthiourea, [CoCl2(detu)2], is reported. The metal(II) complexes are four coordinated with two molecules of the alkyl thiourea and two molecules of either chloride or acetate ions. The compounds are nonelectrolytes in solution and the spectroscopic analysis is consistent with the proposed structures. The complexes were screened against six bacteria isolates to determine their antibacterial potentials.
