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]C—C group, with B—C[triple-bond]C and C[triple-bond]C—C angles of 177.15 (16) and 176.64 (17)°, respectively.
