4,7,9,11,14-pentanitro-2,4,7,9,11,14-hexaazatricyclo［8·4·0·0^3.8］tetradecane-5，6，12，13-difuroxan (PHTTD)［Ⅱ］ and 2-acltyl-4,7,9,11,14-pentanitro-2,4,7,9,11,14-hexaazatricyclo［8·4·0·0^3.8］ 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.
