The title compound, C24H22N2O2P2, contains a diphosphazane backbone, as well as a hydrazine entity. The P—N—P diphosphazane unit and the N-amine N atom are almost coplanar, and the O atoms of the Ph2P(O) units are oriented trans to each other with respect to the P...P axis. In the crystal, centrosymmetrically related mol­ecules are linked into dimers by pairs of N—H...O hydrogen bonds, forming rings of graph-set motif R22(10).

The title compound, C24H22N2OP2, is an asymmetrically substituted hydrazine derivative bearing a phosphoryl and a phosphanyl substituent. The PNNP backbone has a torsion angle of −131.01 (8)°. In the crystal, mol­ecules form centrosymmetric dimers by inter­molecular N—H...O hydrogen bonds, which are further linked into a three-dimensional network by weak C—H...O and C—H...π inter­actions.
