In the title 2:1 crown:cation complex, Li+ is hexaacoordinate. The space group of the crystal is P21/c, with a = 11.7842 (3), b = 14.1405 (4), c = 14.2322 (3), β = 89.90 and Z = 4. The two benzo-10-crown-3 units are nonequivalent in the complex as a result of the spatial disposition of the anion and the 13C CPMAS spectrum is consistent with such a structure.
