摘要：The work reported in this study deals with synthesis, characterization and structural investigation of some newcompounds including novel methods for the synthesis of some metal carbonates. Metal(II) carbonate, MCO3, is obtained bya new very simple synthetic method involving the reaction of aqueous solutions of some metal ions with urea at ~ 90 oC.The infrared spectrum of the formed product clearly indicates the absence of bands due to urea and shows the characteristicbands of carbonate ion. The (CO32-) ion is planar and therefore, it belongs to the D3h symmetry. It is expected to display fourmodes of vibration, A`1 + A"2 + 2E` (E` is a doubly degenerate motion). The zinc(II) and cobalt(II) carbonates, respectively,were performed using a new chemical procedure through the interaction of Zn(HCOO)2.xH2O and Co(HCOO)2.xH2O inaqueous solution with a urea as a simple organic precursor at ~ 90 oC for 12 hrs.
