چکیده
In the title compound, {(C(20)H(20)N(4))(2)[Mo(8)O(26)]}(n), the asymmetric unit contains half of an [Mo(8)O(26)](4-) anion and one 3,3'-[(biphenyl-4,4'-di-yl)dimethyl-ene]diimidazol-1-ium dication. In the anion, four distorted [MoO(6)] octa-hedra are connected via edge-sharing, forming an [Mo(4)O(13)](2-) building block, composed of Mo-O(t), Mo-O(μ2), Mo-O(μ3) and Mo-O(μ4) units, with Mo-O distances ranging from 1.6858 (15) to 2.4785 (13) Å. The γ-type [Mo(8)O(26)](4-) anion is completed by crystallographic inversion symmetry and is linked into an infinite chain along [100] by corner-sharing. The anionic chains and the cations are joined by N-H⋯O hydrogen bonds, generating layers extending parallel to (001).
