The molecular structures of four cyclic (phosphoranylidene)aminophosphazenes were determined. These compounds are small-molecule models for the corresponding high polymeric phosphazenes. The solid-state structures of gem-N3P3Cl4[NP(OPh)3]24, gem-N3P3(OPh)4[NP(OPh)3]25, N3P3(OPh)5NP(OPh)36 and N3P3(NHPr)5NP(NHPr)3·HCl 7 were determined by single crystal X-ray diffraction. Structural parameters: 4, triclinic
