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).
