Abstract
Two new lead selenite oxychlorides, Pb-3(SeO3)(SeO2OH)Cl-3 and Pb-3(SeO3)(2 )Cl-2, have been synthesized by a low temperature (T similar to 160 degrees C) reflux method. This method enabled us to synthesize the compounds in hig h yield, 62% and 81% for Pb-3(SeO3)(SeO2OH)Cl-3 and Pb-3(SeO3)(2)Cl-2, resp ectively, and as crystals. Both materials contain lead(II)-oxychloride grou ps linked to selenium-(IV)-oxide moieties. Additional experiments indicate that Pb-3(SeO3)(SeO2OH)Cl-3 can be irreversibly converted to Pb-3(SeO3)(2)C l-2 with a concomitant loss of HCl.
