The structures of new phosphazene derivatives were characterized by means of elemental analysis, IR and NMR (H-1, C-13, and P-31) spectroscopic techniques. The molecular and crystal structures of mono and tetra vanillinato-substituted monospirocyclotriphosphazenes were examined using X-ray crystallography. The thermal degradation properties of all new compounds were determined using thermal gravimetric analysis (TGA) techniques.eninfo:eu-repo/semantics/closedAccesscyclophosphazenevanilline2,2 '-dihydroxybiphenylspectroscopythermal analysisArticle10.1134/S10703632211202762-s2.0-85122918478256312Q4255491WOS:000743568400027Q4
