THE CRYSTAL STRUCTURE OF ANTIMONY (III) SULFOBROMIDE, SBSBR,
Abstract
The structure of SbSBr was refined by means of Fourier syntheses on (001). There are four units of SbSBr in the unit cell for which a = 8.26, b = 9.79 and c = 3.97 A. The space group is Pnam and the atoms all lie in the mirror planes at z = 1/4 and z = 3/4. The refinement resulted in shifts of as much as 0.4 A in the bond distances. The interpretation is a structure consisting of pleated chains of Sb and S atoms along the c axis with bromine present as Br(-) outside the chains. Each Sb has one S atom at 2.49 A and two S atoms at 2.67 A. Each S atom is similarly bonded to three Sb atoms. The bond angles around Sb are 84.1 degrees (2) and 96.3 degrees (1) while those around S are 95.9 degrees (2) and 96.3 degrees (1). The nearest neighbors of Br(-) are two Sb at 2.94 A and one S at 3.46 A. (Author)
