The condensation reactions of partly substituted spiro and ansa phcnoxycyclotriphosphazenes 1 and 2 with tert-butylamine produce disubstituted geminal-bis(tert-butylamino)phenoxycyclotriphosphazene derivatives (3 and 4). The structures of these compounds were characterized by elemental analysis, and IR, H-1-, C-13-, P-31-NMR and mass spectroscopic techniques. Compound 3 was also examined by X-ray crystallography and found to be crystallized in the monoclinic space group P2(1)/n with the unit cell parameters: a = = 10.842(4), b = 9.375(5), c = 29.104(11) angstrom, beta = 99.25(3), V= 2920(2) angstrom(3), D-x = 1.404 g cm(-3).
