چکیده
In the title compound, C(26)H(25)NP(2), the diphenyl-phosphino groups are staggered relative to the PNP backbone, even though the ethyl substituent coordinated to the N atom is not sterically bulky. The N atom adapts an almost planar geometry with two P atoms and a C atom of the allyl group attached to it in order to accommodate the steric bulk of the phenyl groups and the alkyl group. The distortion of the trigonal-pyramidal geometry of the nitro-gen is further illustrated by the bond angles which range between 114.0 (1) and 123.7 (1)°. There are no classical inter-molecular inter-actions.
