| Description | The title compound, C20H21N2O2P, was synthesized from (RS)(C6H5O)P(O)Cl(NHC6H4-p-CH3) and benzylamine. The product crystallizes as a racemate in a polar space group. The phosphorus atom has a distorted tetrahedral configuration: the bond angles at the P atom are in the range 103.2 (1)-118.4 (1)degrees. The P-N(benzylamido) bond [1.615 (2) angstrom] is slightly shorter than the P-N(p-tolylamido) bond [1.630 (2) angstrom]. Both N-H groups adopt an anti orientation relative to the phosphoryl group. In the crystal, the adjacent molecules are linked via N-H center dot center dot center dot O hydrogen bonds, forming R-2(2)(8) rings, into a one-dimensional arrangement parallel to the x axis. |
