The manganese(II), cadmium(II), magnesium(II) and calcium(II) carbonates, respectively, were achieved by a novel synthetic route through the reaction of aqueous solutions of Mn(HCOO) 2 .xH 2 O, Cd(HCOO) 2 , Mg(HCOO) 2 .2H 2 O, or Ca(HCOO) 2 with a low cost precursor like urea at ~ 85 o C for 12 hrs. The infrared spectra of the results indicate absence of the individual bands of urea, but exhibited of the characteristic bands of ionic carbonate, CO 3 2-. A general reaction mechanisms describing
