The title compound, C6H14Cl4N2OP2, has an acyclic monophosphazene skeleton and a bulky diisopropylamino side group. The bulky substituent is instrumental in determining the molecular geometry. The P-N bonds have neither single-nor double-bond character and are substantially shorter than the ideal P-N single bond. The P-N-P angle [134.0 (2)degrees] is similar to the angle found in cyclotetraphosphazenes, but wider than that in cyclotriphosphazenes.
