New  and  simple  synthesis  method  was  used  to  obtain  lead  (II)  carbonate,  PbCO₃.H₂O,  from  the  reaction  of  aqueous  solutions  of  Pb(NO₃)₂  or  Pb(CH₃COO)₂ salts with urea at elevated temperature at ca.~70°C. Similar reaction using PbCl₂ salt produced the interesting polychloride [Pb₂(NH₂)₂](Cl₁₅)₂. The reaction products were characterized through elemental analysis, infrared spectra and thermal analysis (TG) and (DTG). The infrared spectra of the carbonate products are the same as those of the commercially obtained carbonates. The infrared spectrum of [Pb₂(NH₂)₂](Cl₁₅)₂ shows the characteristic ν_as(N-H) and ν_s(N-H) for the bridged amide groups at 3509 and 3375 cm^-1, respectively, while the δ(NH₂) are observed at 1551 and 1340 cm^-1. The polychloride, Cl₁₅^- exists as (Cl₃^-) ….(Cl₂)₆ in agreement with the observation of  ν(Cl-Cl)  vibrations at 687 and 589 cm^-1 for (Cl₂)₆ unit. The observed bands at 236, 228 and 149 cm^-1 are characteristic for the Cl₃^- unit and are assigned to ν_s(Cl-Cl), ν_as(Cl-Cl) and δ(Cl₃), respectively. The observation of those three infrared active bands indicates that the Cl₃^- unit could be non-linear with C_2v symmetry. Thermal analysis measurements for both the carbonate and the polychloride products are also obtained and discussed.
