N,N'-Dibenzyl-N,N'-dimethyl-N''-(methyl-sulfon-yl)phospho-ric triamide
Abstract:
In the title compound, C(17)H(24)N(3)O(3)PS, the P and the S atoms are each in a distorted tetra-hedral environment and the N atoms display sp(2) character. The phosphoryl group and the NH unit are anti with respect to one another. The dihedral angle between the mean planes of the benzene rings is 31.08 (8)°. The crystal packing is stabilized by N-H⋯O hydrogen bonds, forming an extended chain parallel to the b axis.
