Bis[2-(morpholinometh-yl)phen-yl]phenyl-phosphane.

The title compound, C28H33N2O2P, contains a penta­coordinated P atom as a result of the weak N→P intra­molecular inter­actions, with three C atoms, two N atoms and the lone pair arranged in a dicapped pseudo-tetra­hedral geometry. The morpholine rings exhibit an almost ideal chair conformation. In the crystal, two weak C—H⋯O hydrogen-bond inter­actions link the mol­ecules in layers stacked along the a axis; there are no further inter­actions between the layers.
