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 C—C group, with B—C C and C C—C angles of 177.15 (16) and 176.64 (17)°, respectively.

We have shown that {closo-CB11} clusters with one or two alkynyl groups bonded to boron are accessible by Pd-catalysed Kumada-type cross-coupling reactions starting from the corresponding mono- and diiodinated clusters, see: Finze (2008, 2009)
