Tetrakis(2-methylbenzimidazolium) β-octamolybdate(VI)
Abstract
The asymmetric unit of the title compound, (C8H9N2)4[Mo8O26], consists of two 2-methylbenzimidazolium cations and one-half of a β-Mo8O264− anion, which is completed by crystallographic inversion symmetry. An extensive net of N—H...O hydrogen bonds between the cations and anions contribute to the crystal packing.
