Dicyclohexyl(4-isopropylphenyl)phosphane selenide

Abstract

In the title compund, C21H33PSe, the Se=P bond is part of a distorted tetra­hedral environment on the P atom. Both cyclo­hexyl groups adopt chair conformations. A cone angle of 170° was calculated using an adaptation of the Tolman model. Inter­molecular C—H⋯Se and C—H⋯Cg contacts are observed (Cg is the centroid of the benzene ring).
