Octadecaborane(22), B18H22, is a polynuclear borane used in the semiconductor industry.

It is structurally related to decaborane(14): the structure can be viewed as two fused arachno-decaborane units sharing two boron atoms. The usual form of octadecaborane(22) is the anti-fused structure, also referred to as n-B18H22.

It is prepared by the oxidation of the B9H12 cluster, for example with iodine in toluene solution.[1][2]
