The sulphur and selenium atoms are both disordered over two 
positions, with the refined percentage occupancy ratio between 
the major and minor positions (labelled Se/S and S'/Se' 
respectively), being 69.8 (3) : 30.2 (3).
The hydrogen atoms were added at calculated positions and 
refined by use of a riding model with the isotropic 
displacement parameters based on the equivalent isotropic 
displacement parameter (Ueq) of the parent atom.
