| Abstract: | The so-called “ammoniacal zinc carbonate”, which is known to lead by thermolysis to a non stoichiometric pink zinc oxide, is shown to be an ammine complex and not an ammonium salt. From chemical analysis and cristalline structure, the formule is NH3ZnCO3. Ammonia is directly bond to zinc atom and not to carbonate anions by hydrogen bonding. This compound provides a quite strong non linear optical effect in visible frequency. |
