octanitrocubane
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.

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.
It is, however, not as powerful an explosive as once thought, as the high-density theoretical crystal structure has not been achieved. For this reason, heptanitrocubane, the slightly less nitrated form, is believed to have marginally better performance, despite having a worse oxygen balance.
