[2-(4-Methylpiperazin-1-ylmethyl)-phenyl]diphenyl-phosphane

Abstract

In the title compound, C24H27N2P, the P atom is bonded to three C atoms in a trigonal-pyramidal geometry. The overall -trigonal-bipyramidal coordination of the P atom is established when the contribution of the electron lone pair and of the N - P donor-acceptor distance of 3.051 (3)Å are considered. The 4-methyl-piperazinyl ring adopts a chair conformation. Intra- and inter-molecular C - H⋯π hydrogen bonding leads to the consolidation of the structure.
