2-Isobutyl-2-phosphabicyclo[3.3.1]nonane 2-selenide


The title compound, C12H23PSe, represents the first structure of a phosphine containing the bicyclic 2-phosphabicyclo[3.3.1]nonane (VCH) unit. It contains two chiral centres per molecule which can be either R,R- or S,S and crystallizes as a centrosymmetric, racemic micture of the enantiomers. The P—Se bond distance of 2.1360 (16) Å is typical for these compounds. The Tolman cone angle (2.28 Å from P) was calculated as 163°, and the effective cone angle (using the crystallographically determined P—Se bond distance) is 168°
