[2-(4-Methyl-piperazin-1-ylmeth-yl)phen-yl]diphenyl-phosphane.

In the title compound, C(24)H(27)N(2)P, the P atom is bonded to three C atoms in a trigonal-pyramidal geometry. The overall Ψ-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.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
