Nitrogen-rich　high　density　metal-organic　frameworks　(MOFs)　can　be　used　as　a　new　type　of　energetic　materials.　The　energetic　MOFs　provide　a　new　method　to　reconcile　contradiction　between　high　energy　and　reliable　safety　in　energetic　materials.　Framework　interpenetration　would　be　an　effective　approach　to　reduce　the　pore　volume　and　meanwhile　to　enhance　the　structural/chemical　stabilities　of　the　target　energetic　MOFs.　In　this　work,　mixed　ligands　of　5-aminotetrazole　(HATZ)　and　tetrazole　(HTZ)　were　chosen　to　assemble　with　Zn(II)　ions　with　the　purpose　to　prepare　interpenetrated　MOF　materials　with　insensitivity.　Ultimately,　a　high-density　3D　energetic　compound,　[Zn-2(ATZ)(2)(TZ)(2)](n)　(1)　was　in　situ　isolated　under　simple　hydrothermal　conditions.　In　the　crystal　structure　of　1,　there　existed　two　independent　3D　diamond　networks,　which　were　formed　by　Zn1(II)　ions/TZ(-)　ligands　and　Zn2(II)　ions/ATZ(-)　ligands,　respectively.　These　two　independent　3D　diamond　networks　were　interpenetrated　to　each　other　to　construct　a　3D　condensed　high-density　framework.　The　standard　molar　enthalpy　of　formation　(Delta　H-f　degrees)　of　1　was　deduced　as　1786.45　kJ/mol　(4.09　kJ/g),　which　to　date　still　occupies　the　status　of　the　top　high　Delta　H-f　degrees　value　among　the　reported　energetic　MOF　materials.　Conducted　sensitivity　measurements　demonstrated　the　insensitivity　of　1　to　external　mechanical　stimuli.　TGA　showed　1　had　good　thermal　stability　up　to　332　degrees　C,　whereas　the　decomposition　temperature　of　pure　HATZ　and　HTZ　ligands　are　207　and　174　degrees　C,　respectively.　This　shows　that　the　greater　stability　of　1　could　be　attributed　to　the　structural　reinforcement　induced　by　the　effect　of　coordination　polymerization　and　framework　interpenetration.　Compound　1　can　serve　as　a　promising　energetic　material　with　a　high　level　of　safety　because　of　its　good　energetic　properties,　insensitivity,　and　high　thermal　stability.
