Abstract
In the title molecule, C19H25N2O2P, the P atom is bonded in a distorted tetrahedral environment. The dihedral angle between the two phenyl rings is 89.09 (8)°. The methyl H atoms are disordered over two sets of sites with equal occupancy. The O atom of the P=O group acts as a double hydrogen-bond acceptor of the type (N—H)2⋯(O=)P—, forming R22(8) rings which are further linked into chains along [010].
