N2 ka mohiotia anake te ahua hangahanga koretake me te pumau (allotrope) o te hauota. Te whakahiato o N3 a N4 i ripoatahia i mua atu engari kaore i taea te wehe na te tino koretake. Kua angitu nga kairangahau ki te whakahiato i te pāmahana rūma o te hexnitrogen (N6), he allotrope hou o te hauota ka taea e ratou te mahanga i roto i nga matrices argon i te 10K. Ko te whakahiato o N6 i whakapumauhia ma te matakite, a, i kitea te allotrope hou he pumau. Ko te tauhohenga whakapoapoa he mea whakamaarama me te tukunga o te nui o te kaha e kii ana ka taea te whakamahi hei hangarau rokiroki pūngao i raro i te whakaritenga o te pāmahana hauota wai. Ahakoa tenei, ko te whakarite i tetahi kaapapa hou, he tohaa hauota he mea nui te whanaketanga o te matū.
Ko nga Allotropes he momo hanganga rereke o tetahi huānga ka puta mai i nga momo hononga rereke o nga ngota o te huānga kotahi. He rereke nga ahuatanga i runga i to raatau hanganga, he utu-kupapa kei roto i nga ahua kore. Hei tauira, taimana, kauwhata, me graphene he kūpapa, pūmau allotropes o te waro. He pera ano a O2 ko O3 (ozone) allotropes o te hāora.
He aha te ahua o te hauota hauota, te hanga koretake? Ko te pai tawhito N2 ka mohiotia anake te allotrope pūmau o te hauota. E rua etahi atu allotropes N3 a N4 i ripoatahia i mua i te tau 1956 me te tau 2002 engari kaore i taea te wehe na te tino koretake.
Kua oti pai te whakahiato e nga tohunga matū a C2h-hexnitrogen hangarite (C2h-N6) i te ruma-mahana. [C2h Ko te hangarite he momo hangarite e kitea ana i te ao matū. AC2h-i te rāpoi ngota hangarite he tuaka hurihanga-rua (C2) me te rererangi whakaata whakapae (σh)].
Hexnitrogen (N6), i whakahiatotia te allotrope hou o te hauota i te pāmahana rūma na roto i te tauhohenga hau-waa o te maota (Cl2) me te bromine (Br2) me te azide hiriwa (AgN3) i raro i te pehanga iti. I whai muri mai ko te mahanga cryogenic i roto i nga matrices argon i te 10 Kelvin. I taea ano e nga kairangahau te whakarite hexnitrogen i roto i te ahua parakore hei kiriata i te 77 Kelvin (te waahi kohua o te hauota wai).
Hexnitrogen (N6) na te mea i whakaritea i roto i te taiwhanga i tohuhia ma te matakite me te whakaatu he pumau.
I runga i te pirau, hexnitrogen (N6) ka pakaru ki te toru N2 ngota ngota. He exothermic te tauhohenga me te tukunga o te 185.2 kcal mo ia mole o te kaha, e 2.2 me te 1.9 nga wa teitei ake i te kaha i tukuna i runga i te pirau o te TNT me te HMX i te taumaha. Na te nui o te tukunga o te kaha i runga i te pirau, hexnitrogen (N6) tera pea he rauemi putunga puonga ma, engari me pupuri te hexnitrogen i te hau hauota wai i raro iho i te 77K kare pea e pai mo te hangarau rokiroki hiko.
Ahakoa te tono a muri ake nei, he whanaketanga nui te whakarite i te pāmahana rūma o tenei allotrope ngota ngota hou o te hauota ka mau ki roto i te waahi cryogenic he whanaketanga matū.

, a new neutral allotrope of nitrogen which they could trap in argon matrices at 10K. The synthesis of N6 was confirmed spectroscopically and the new allotrope was demonstrated to be stable.){kind=link}
