(see the right part of Fig. ???Fig.1c)1c) and 2 ?? above and below the center of the B12H6molecule (NICS(1) = ???3.9 ppm; NICS(2) = ???5.2 ppm).The benzene dimer is the simplest prototype of the aromatic ??????? interactions which is an important weak interaction present in aromatic supramolecular systems
