The coordination around the N atom in the title compound, C(29)H(29)NP(2), shows an almost planar geometry, defined by the attached P and C atoms, in order to accomodate the steric bulk of the phenyl rings. The distortion of the trigonal-pyramidal geometry of the N atom is illustrated by the bond angles ranging between 115.22 (12) and 121.76 (9)°. The P atoms present a pyramidal environment with bond angles ranging from 100.62 (9) to 104.71 (8)°. One of the C atoms in the cyclo-pentyl ring displays a 0.822 (4):0.178 (4) positional disorder. Within the crystal structure, intra-molecular C-H⋯P hydrogen bonds together with inter- and intra-molecular C-H⋯π inter-actions link the mol-ecules into a supra-molecular two-dimensional network.
在标题化合物C₂₉H₂₉NP₂中，N原子周围的配位呈现出近乎平面的几何构型，由相连的P和C原子确定，以容纳苯环的空间位阻。N原子三角锥几何构型的畸变由115.22 (12)°至121.76 (9)°的键角范围体现。P原子呈现出锥角范围为100.62 (9)°至104.71 (8)°的棱锥环境。环戊基环中的一个C原子表现出0.822 (4):0.178 (4)的位置无序。在晶体结构中，分子内C—H⋯P氢键以及分子间和分子内C—H⋯π相互作用将分子连接成一个超分子二维网络。
