The N-H...O hydrogen bond is the characteristic interaction in the crystal structures of N-benzyl-P-phenyl-N'-(p-tolyl)phosphonic diamide, CHNOP or (CH)P(O)(NHCHCH)(NHCH-p-CH), (I), diphenylphosphinic 1-methylpropylamide, CHNOP or (CH)P(O)[NHCH(CH)(CH)], (II), (S)-1-phenylethylammonium N-[(S)-1-phenylethyl]phenylphosphonamidate, CHN·CHNOP or [S-(CH)CH(CH)NH][(CH)P(O){S-NHCH(CH)(CH)}(O)], (III), and (4-methylbenzyl)ammonium diphenylphosphinate, CHN·CHOP or [4-CH-CHCHNH][(CH)P(O)(O)], (IV). This article focuses on the N-H...O hydrogen bonds by considering the structures of (I), (II), (III) and (IV), and reviewing their analogous compounds, including 43 (C)P(O)(N), 102 (C)P(O)(N), 31 (C)P(O)(N)(O) and 96 (C)P(O)(O) structures, deposited in the Cambridge Structural Database (CSD). For the structures with a (C)P(O)(N) segment, only neutral hydrogen bonds were found in the CSD. The other three classes of compounds included both neutral and `charge-assisted' hydrogen bonds, and the (C)P(O)(O) structures were particularly noticeable for a high number of cation-anion compounds. The overall tendencies of N...O distances in neutral and cation-anion compounds were compared. The N-H...O hydrogen-bond angles were also analyzed for the four classes of phosphorus compounds.

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 R 2 2(10).
