Octaazacubane /ˌɒktəˌeɪzəˈkjuːbeɪn/ is a hypothetical explosive allotrope of nitrogen with formula N8, whose molecules have eight atoms arranged into a cube. (By comparison, nitrogen usually occurs as the diatomic molecule N2.) It can be regarded as a cubane-type cluster, where all eight corners are nitrogen atoms bonded along the edges. It is predicted to be a metastable molecule, in which despite the thermodynamic instability caused by bond strain, and the high energy of the N–N single bonds, the molecule remains kinetically stable for reasons of orbital symmetry.

  • L'octaazacubane est un allotrope hypothétique de l'azote de formule N8. La molécule d'octaazacubane prend la forme d'un cube où tous les huit sommets sont des atomes d'azote liés entre eux par les arêtes comme dans le cubane où ce sont des radicaux ≡CH qui sont aux sommets. (fr)

  • 옥타아자큐베인(Octaazacubane)은 질소 원자 여덟개가 정육면체의 꼭지점에 위치하는 분자이다. 질소의 단일결합은 삼중결합의 ⅓보다 약하기 때문에 폭발성을 갖고 있다. 오비탈의 대칭성때문에 화학반응속도론적으로는 안정하지만 열을 받아 질소분자로 분해되면 TNT의 5배에 달하는 폭발력을 낸다. (ko)
  • オクタアザキュバン(Octaazacubane)は、化学式N8で表される仮説上の窒素の同素体である。分子は8つの窒素原子を含み、立方体状に配列する。キュバンの8つの炭素原子及びそれに結合する水素原子が全て窒素原子に置き換わった誘導体とみなすこともできる。準安定状態にあると予測され、そのやN-N単結合の高エネルギーにもかかわらず、分子対称性のおかげで分子は反応速度論的に安定である。 (ja)
  • O Octaazacubano é um alótropo hipotético do nitrogênio com fórmula N8, cujas moléculas possuem oito átomos dispostos em um cubo. (Em comparação, o nitrogênio ocorre naturalmente na molécula diatômica N2.) Pode ser considerado um cluster do tipo cubano, em que todos os oito vértices são átomos de nitrogênio ligados pelas arestas. É prevista como uma molécula metaestável, isso é, apesar da instabilidade termodinâmica causada pela tensão de ligação e da alta energia das ligações simples N–N, a molécula se mantém cineticamente estável por razões de simetria orbitalar.

  • 八氮立方烷也称为“立方氮烷”,是氮元素的一种假想单质,分子式为N8。八氮立方烷与N2、N4等互为同素异形体。八氮立方烷分子由8个围成立方体氮原子构成,可以看作所有次甲基都被氮原子代替了的立方烷分子,所以八氮立方烷是立方烷的衍生物之一。八氮立方烷分子可能是一种。若忽略由引起的化学热力学不稳定性和的较高键能,只从化学动力学角度来看,该分子因轨道对称而具有一定稳定性。 (zh)
