The title compound, (C12H11N3)2[Mo8O26], was prepared by the hydro­thermal method. The centrosymmetric β-octa­molybdate anions are linked to form a three-dimensional structure by the 2-(4-pyridinio)benzimidazolium cations through N—H...O hydrogen bonds.

Experimental. Both cell_measurement_temperature and cell_ambient_temperature are 293 K.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. The structure was solved by direct methods, and refined by the full least-squares method against F2. All non-H atoms were refined with anisotropic displacement parameters. All calculations were performed on a computer with SHELXTL-PC program package. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
