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)
