A New Method to Prepare Polycrystalline Meta-Thioboric Acid, (HBS2)3

Abstract

Thioacids (ex: thioboric acid) are important precursors in exploring new chalcogenide ceramic and glassy materials. We report here a new facile method to prepare crystalline meta-thioboric acid (c-(HBS2)3). c-(HBS2)3 was prepared by reacting H2S with B2S3, in the vapor phase and the product was obtained as a vapor condensate. The technique is fairly simple and quick compared to the time consuming and wet routes of thiolysis of boron tribromide. The reaction takes place at much lower temperatures and in the vapor phase, thus achiveing higher purity.
