“…The P-N-P bond angles are a little larger than the N-P-N bond angles and the average value of P-N-P angles is 121.55 • (Table S1). Thus, the P-N bond lengths are in the normal ranges and all of these bond parameters were compatible with those reported for fully substituted cyclotriphosphazene derivatives [29,40,41].…”

In this study, a series of cyclotriphosphazene derivatives containing a Schiff base (3a-3d) were synthesized by the reactions of hexachlorocyclotriphosphazene (1) with bis-aryl Schiff bases (2a-2d) having different terminal groups (H, F, Cl, and Br). The products (3a-3d) were characterized by elemental and mass analyses, FT-IR, and 1 H, 13 C, and 31 P NMR spectroscopies. Furthermore, the structure of compound 3a was also determined by X-ray crystallography. The thermal behaviors and the spectral properties of the new cyclotriphosphazene compounds (3a-3d) were investigated and the results were compared in the series.
