Abstract

The crystal structure of 5,5-dimethyl-2-(p-methylanilino)-2-oxo-1,3,2-diazaphosphorinane has been determined. The P-N bond lengths are significantly shorter than the P-N single bond. The P=O bond is placed in an equatorial position and is slightly longer than the PO double bond length. The molecule is obtained in the form of a two dimensional polymer via intermolecular -N-H…O=P- and -N-H…N- hydrogen bonds. A weak C-H…O hydrogen bond is also observed in the structure.
