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 14 and z 34. 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.
