Example of an intramolecular, non-classical C–H⋯π hydrogen bonding interaction in an Arylcarborane derivative

The synthesis and X-ray diffraction study of 3-(2-biphenyl)-1,2- C2B10H11, 1, provides an example of an intramolecular non-classical C–H⋯π hydrogen bonding interaction in which the same aromatic π-electron-donating group which interacts with the carborane C–H is also connected to the carborane cage.
