In the present study, urea metal complexes formed in the reaction of urea (U) with Cu(II), Zn(II), Ag(I), Cd(II) and Hg(II) ions have been investigated at 90o C. These were characterized through electronic and infeared spectra as well as elementally, magnetically and conductively analysis. The obtained results showed that the formed complexes have the formulas (CuCl2)2.U.CH3OH.6H2O, (ZnCl2)2.U.CH3OH.6H2O, AgNO3.U.CH3OH.2H2O, (CdCl2)2.U.2CH3OH.2H2O and (HgCl2)2.U.CH3OH.6H2O in full agreement with the known reaction stoichiometries as well as the elemental measurements. The high values of molar conductivity of some of the resulting urea complexes show them to be electrolytes in nature.
