Article: Crystal structure of semiorganic antimony thiourea bromide monohydrate crystals: a redetermination.(Report)

1. Introduction

In the work of growing semiorganic crystals of antimony thiourea bromide monohydrate (ATBM), thiourea, which is a typical polar molecule, was selected to combine with antimony bromide. Bhat and Dharmaprakash [1] have grown single crystals of ATBM in sodium meta silicate gel at ambient temperature. Here ATBM crystallizes in the orthorhombic system with space group [Cmc2.sub.1]. It can also be known from the structure analysis that antimony bonds with sulphur or not. Shettigar et al. [2] studied the structure of antimony thiourea bromide hydrate grown by gel technique with the molecular formula Sb[[CS[(N[H.sub.2]).sub.2]].sub.2][Br.sub.3] x ...
