Synthesis, characterization, thermal decomposition, and antimicrobial studies of copper(I) complexes of 1,3-dihydro-4,5-di(4-methoxyphenyl)imidazolin-2-thione

The reaction between 1,3-dihydro-4,5-di-(4-methoxyphenyl)imidazolin-2-thione (MDPIT) with seven different copper(II) salts were carried out to synthesize and characterize the corresponding complexes. These complexes have the general formulae [CuLX(H2O)], where X = OAc, Cl, Br, NO3 , ClO4 or CNS, and [Cu2L2(SO4)(H2O)]. Characterization of the complexes was done by chemical analyses, molar conductance, magnetic susceptibility, electronic, infrared and H-1 NMR spectral studies. Thermogravimetric studies of complexes were carried out and kinetic parameters for the various decomposition stages were also calculated. Preliminary investigations on the antifungal and antibacterial activities of the ligand and some of its complexes were also made.
