Abstract:
In the title compund, C(21)H(33)PSe, the Se=P bond is part of a distorted tetra-hedral environment on the P atom. Both cyclo-hexyl groups adopt chair conformations. A cone angle of 170° was calculated using an adaptation of the Tolman model. Inter-molecular C-H⋯Se and C-H⋯Cg contacts are observed (Cg is the centroid of the benzene ring).
