In the title compound, C(31)H(27)NP(2), the diphenyl-phosphanyl groups are staggered relative to the PNP backbone. The N atom is displaced by 0.219 (2) Å from the plane formed by the two P atoms and the methylene C atom. The angles around the N atom are 120.84 (16), 113.29 (16) and 120.57 (12)°, indicating that it exhibits a distorted trigonal-pyramidal geometry. There are no classical inter-molecular inter-actions.
