Abstract

The series of four cyclotriphosphazenes containing biphenyl and phenyl groups, [N3P3(C12H8)3- nPh2n], where n = 0–3, (1–4 respectively), has been completed by the synthesis of two new C-bonded spiro-cyclotriphosphazenes, [N3P3(C12H8)2Ph 2] 2 and [N3P3(C12H8)Ph4] 3. They have been fully characterised and X-ray structural analysis shows that both compounds have a planar cyclotriphosphazene ring with less overall molecular rigidity compared to the trispirocyclic analogue, 1.
