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.

Structure description
The title compound C24H22N2OP2 (Fig. 1) is an asymmetrically substituted hydrazine derivative containing a phosphoryl and phosphane entity. The PNNP backbone has a torsion angle of −131.01 (8)°. As a result of the asymmetrical substitution, the P—N bond lengths have significantly different values. Even if both P—N bond lengths are shortened when compared to the sum of the covalent radii calculated by Pyykkö (2015) [single: Σrcov(P—N) = 1.82 Å, double: Σrcov(P—N) = 1.62 Å], the PV—N distance [P1—N1 = 1.6561 (11) Å] is noticeably shorter than the PIII—N distance [P2—N2 = 1.7049 (11) Å]. The more pronounced reduction of PV—N bond lengths of phosphoryl hydrazine entities [range from 1.6587 (15) to 1.6989 (10) Å; Gholivand et al., 2012, 2016; Höhne et al., 2018] in comparison to phosphane hydrazine PIII—N distances [range from 1.692 (2) to 1.728 (2) Å; Kriel et al., 2010; Aluri et al., 2010; Sushev et al., 2008] is documented. The N—N distance within the hydrazine unit amounts to 1.4256 (16) Å and conforms to the sum of the covalent radii calculated by Pyykkö (2015) [Σrcov(N—N) = 1.42 Å].
In the crystal, centrosymmetrically related molecules of the title compound are linked by pairs of intermolecular N—H⋯O hydrogen bonds (Table 1) forming dimers, which are further linked by weak C—H⋯O and C—H⋯π interactions into a three-dimensional network.
Synthesis and crystallization
A solution of NEt3 (7.7 ml, 55.0 mmol) in THF was added to another solution of N2H4·HCl (0.685 g, 10.0 mmol) and Ph2PCl (3.7 ml, 20.0 mmol) in THF (20.0 ml). The mixture was stirred for 24 h at room temperature. Afterwards it was filtered; the solvent was removed in vacuum. 7.0 ml of toluene were added. The microcrystalline product was identified by NMR to be (Ph2P)2N—NH2. During the repeated attempts to crystallize (Ph2P)2N—NH2, the compound could have had some air contact, followed by rearrangement. The title compound was recrystallized from toluene.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. The N-bound hydrogen atoms H1 and H2B could be found from the difference Fourier map and were refined freely. All other H atoms were placed in idealized positions with d(C—H) = 0.95 Å and refined using a riding model with Uiso(H) fixed at 1.2 Ueq(C). |
