چکیده
The title compound, C(20)H(26)NO(4)P, has been obtained by the reaction of benzoyl chloride and diisoprop-yl[amino-(phen-yl)meth-yl]phospho-nate. The dihedral angle between the planes of the benzoyl-amino group and the phenyl ring is 77.0 (2)°. The crystal structure is stabilized by strong inter-molecular N-H⋯O hydrogen bonds between the doubly bonded phosphoryl O atom and the amide N atom which link the mol-ecules into pairs about a center of symmetry.

Mol-ecules of the title compound, C(34)H(38)N(4)O(2), lie across crystallographic inversion centres. The crystal packing can be described by alternating zigzag chains along the c axis in which the molecules are linked by van der Waals interactions. There is an intra-molecular O-H⋯N hydrogen bond and the two benzene rings in the asymmetric unit make a dihedral angle of 79.81 (6)°.
