八硝基立方烷
Also known as ONC
Octanitrocubane (molecular formula: C8(NO2)8) is a proposed high explosive that, like TNT, is shock-insensitive (not readily detonated by shock). The octanitrocubane molecule has the same chemical structure as cubane (C8H8) except that each of the eight hydrogen atoms is replaced by a nitro group (NO2). As of 1998, octanitrocubane had not been produced in quantities large enough to test its performance as an explosive.

八硝基立方烷（英文：Octanitrocubane，ONC）是一种新型高能炸药，分子式为C8(NO2)8，由立方烷的氢全部被硝基取代制得。它与三硝基甲苯类似，对震动的敏感度比较低，甚至用锤子砸也不会爆炸。 八硝基立方烷中存在张力，碳-碳键的键角为90°，与sp3杂化碳原子的109°28'相差很大；分解产物也是很稳定的二氧化碳和氮气，因此八硝基立方烷的爆炸性非常强，是性能最强的几种炸药之一。它比奥克托今（HMX）的威力大20-25%。 C8(NO2)8 → 8CO2 + 4N2 八硝基立方烷与其分解产物都是无毒的。反应中不产生水，因此基本上不会有烟雾产生。
