N,N'-Dibenzyl-N''-(2-chloro-acet-yl)-N,N'-dimethyl-phospho-ric triamide

In the title mol-ecule, C(18)H(23)ClN(3)O(2)P, the P atom is bonded in a distorted tetra-hedral environment. The P=O and N-H groups are syn with respect to each other. The angles at the tertiary N atoms confirm their sp(2) character. In the crystal, pairs of inter-molecular P=O⋯H-N hydrogen bonds form centrosymmetric dimers.
