In the title compound, C(28)H(27)NP(2), the N atom adopts an almost planar geometry with the two P atoms and the C atom attached to it, with a distance of 0.066 (2) Å between the N atom and the C/P/P plane. The distorted trigonal-pyramidal geometry of the N atom is further illustrated by bond angles ranging between 115.22 (11) and 123.53 (8)°. Bond angles varying from 99.99 (9) to 108.07 (9) ° are indicative of the distorted pyramidal environment around the P atoms. An intra-molecular C-H⋯P hydrogen bond occurs. In the crystal, inter-molecular C-H⋯π inter-actions link the mol-ecules into a supra-molecular network.
在标题化合物C(28)H(27)NP(2)中，N原子与两个P原子及与之相连的C原子形成近乎平面的几何构型，N原子与C/P/P平面之间的距离为0.066 (2) Å。N原子扭曲的三角锥几何构型通过115.22 (11)°至123.53 (8)°之间的键角进一步体现。P原子周围扭曲的锥环境由99.99 (9)°至108.07 (9)°变化的键角表明。分子内存在C—H⋯P氢键。在晶体中，分子间C—H⋯π相互作用将分子连接成超分子网络。
