The synthesis of the title compound, TNDAZ, in four steps by starting with N-t-Butyl-3hydroxymethyl-3-nitroazetidine is described. The structures of TNDAZ and of a precursor, N-t-Butyl-3-nitro-3-N-t-butyl-3-nitroazetidin-3-ylazetidine have been established unequivocally via application of single crystal X-ray crystallographic techniques. Thermal properties of TNDAZ, alone and in admixture with 1, 3,3-trinitroazetidine TNAZ, are presented. In particular, a binary phase diagram has been predicted computationally and confirmed experimentally using the techniques of differential scanning calorimetry and hot stage microscopy. Data support the existence of more than one polymorph for both TNDAZ and TNAZ. p4
