title: Bis[2-(morpholinometh-yl)phen-yl]phenyl-phosphane.
abstract: The title compound, C(28)H(33)N(2)O(2)P, contains a penta-coordinated P atom as a result of the weak N→P intra-molecular inter-actions, with three C atoms, two N atoms and the lone pair arranged in a dicapped pseudo-tetra-hedral geometry. The morpholine rings exhibit an almost ideal chair conformation. In the crystal, two weak C-H⋯O hydrogen-bond inter-actions link the mol-ecules in layers stacked along the a axis; there are no further inter-actions between the layers.
