Abstract: The asymmetric unit of the title compound, C8H20N+·C9H16B11- or [Et4N][12-PhCC-closo-CB11H11], consists of one cation and one anion. The [12-PhCC-closo-CB11H11]- anion is close to possessing a non-crystallographic plane of mirror symmetry with a nearly linear B-C![[triple bond]](/logos/entities/z-tbnd_rmgif.gif)
C-C group, with B-CC and CC-C angles of 177.15 (16) and 176.64 (17)°, respectively.
