Molecular Packing in Crystals of Phenoselenazine
(International Union of Crystallography, 1976)
The crystal structure of phenoselenazine was solved by molecular-packing analysis. Trial models of the rigid molecule were oriented and positioned in the Cheshire cell. The refinement was carried out by structure-factor ...
