In the title mol-ecule, C(17)H(23)N(2)O(2)P, the P atom has a distorted tetra-hedral environment. The P-N bond to the tolyl-amido fragment is 1.642 (4) Å while that to the butyl-amido fragment is 1.629 (3) Å. The dihedral angle between the two benzene rings is 82.3 (2)°. In the crystal, adjacent mol-ecules are linked via weak N-H⋯(O)P and N-H⋯N hydrogen-bonding inter-actions into an extended chain parallel to the b axis. The three methyl groups of the tert-butyl-amido substituent are disordered over two sets of sites with equal occupancies. The crystal studied was found to be a non-merohedral twin with the minor twin component = 23.1 (1)%.
在标题分子C(17)H(23)N(2)O(2)P中，磷（P）原子具有扭曲的四面体环境。与甲苯基酰胺片段相连的P-N键长为1.642 (4) Å，而与丁基酰胺片段相连的P-N键长为1.629 (3) Å。两个苯环之间的二面角为82.3 (2)°。在晶体中，相邻分子通过弱的N-H⋯(O)P和N-H⋯N氢键相互作用连接成平行于b轴的延伸链。叔丁基酰胺取代基的三个甲基在两组占有率相等的位置上无序分布。所研究的晶体被发现是一个非镜像孪晶，次要孪晶组分 = 23.1 (1)%。
