Pentaborane, also called pentaboron nonahydride, stable pentaborane, or pentaborane(9) (to distinguish it from B5H11), is a chemical compound considered in the 1950s as a good prospect for a rocket or jet fuel by both the U.S. and Russian armed services, a so-called "exotic fuel". Its chemical structure is that of five atoms of boron compounded with nine atoms of hydrogen (B5H9); it is one of the boranes. Because simple boron compounds burn with a characteristic green flame, the nickname for this fuel in the U.S. industry was "Green Dragon".
