Abstract:4,7,9,11,14-pentanitro-2,4,7,9,11,14-hexaazatricyclo[8·4·0·03.8]tetradecane-5,6,12,13-difuroxan (PHTTD)[Ⅱ] and 2-acltyl-4,7,9,11,14-pentanitro-2,4,7,9,11,14-hexaazatricyclo[8·4·0·03.8] tetradecane-5,6,12,13-difuroxan·2H2O(APHTTD) [Ⅲ] and PHTTD[Ⅱc] were synthesized from nitration of HTTD[Ⅰ] ; PHTTD·2H2O[Ⅱa] and PHTTD·dioxane[Ⅱb] were synthesized from reaction of PHTTD[Ⅱ] and water( or dioxane). Nitrated products forming molecular complexes with the molecules containing oxygen was general character of furazan and furoxan-fused cylic compounds of nitramines. Their structures were characterized by elemental analysis,IR and MS spectra.
