N,N′-Dibenzyl-N,N′-dimethyl-N′′-(p-tolyl)phosphoric triamide
The asymmetric unit of the title compound, C(23)H(28)N(3)OP, contains two independent molecules with significant conformational differences. For example, the torsion angles N—C—C—C involving the N-benzyl moieties are 57.3 (7) and 11.6 (8)° in one molecule and 76.5 (7) and 97.4 (7)° in the other. I...

Sumario: | The asymmetric unit of the title compound, C(23)H(28)N(3)OP, contains two independent molecules with significant conformational differences. For example, the torsion angles N—C—C—C involving the N-benzyl moieties are 57.3 (7) and 11.6 (8)° in one molecule and 76.5 (7) and 97.4 (7)° in the other. In each molecule, the P atom exhibits a distorted tetrahedral conformation [the bond angles at P are in the ranges 104.7 (2)–115.2 (2) and 105.1 (2)–115.1 (2)° in the two molecules], and the phosphoryl group and the N—H group adopt an anti orientation with respect to one another. In the crystal, molecules are linked via N—H⋯O(P) hydrogen bonds, forming a chain parallel to the a axis. |
