The Crystal Structure of a Spirocyclic Cyclophosphazene N3P3(NMe2)4(NHCH2CH2NH) - Evidence for Intermolecular Hydrogen Bonding

Abstract
An X-ray crystal structure analysis of tetrakis(dimethylamino)(ethylenediamino)cyclotriphosphazene reveals a novel spirocyclic structure with the spiro ring having an envelope conformation. There is evidence for an intermolecular N-H ··· N bond in the crystal which persists in solution
