In the title compound, C(27)H(25)NP(2), the diphenyl-phosphino groups are staggered relative to the PNP backbone. The dihedral angles between the phenyl rings bonded to each P atom are 51.74 (5) and 68.23 (4)°. The coordination around the N atom deviates from trigonal-pyrimidal geometry towards an almost planar arrangement between the N atom and the adjacent P and C atoms; the distance between the N atom and the plane formed by the adjacent C/P/P atoms is 0.098 (2) Å.
在标题化合物C(27)H(25)NP(2)中,二苯基膦基相对于PNP主链呈交错排列。与每个P原子相连的苯环之间的二面角分别为51.74 (5)°和68.23 (4)°。N原子周围的配位从三角锥几何构型向N原子与相邻P和C原子之间几乎平面的排列发生偏离;N原子与相邻C/P/P原子形成的平面之间的距离为0.098 (2) Å。
