The structural study of [2-Cl-C.sub.6./sub.H.sub.4./sub.C(O)NH]P(O)[NHC.sub.6./sub.H.sub.4./sub.-4-CH.sub.3./sub.].sub.2./sub.

A new phosphoric triamide with the formula [2-Cl-C6H4C(O)NH]P(O)[NHC6H4-4-CH3]2 has been investigated by spectroscopic methods and X-ray crystallography. This compound crystallizes in the monoclinic system, with P21/c space group. In this molecule, the P atom has a distorted tetrahedral environment. The N atoms bonded to P atom have mainly sp2 character. In the crystal, the molecules are aggregated through NCP-H…O═P and NP―H…O═C hydrogen bonds in a linear arrangement along the b axis, by forming a sequence of alternate ( ) 8 22 R and ( ) 22 R 12 motifs. Furthermore, C-H…O and C- H…Cl intermolecular interactions complete a 3D structure.
