Abstract :
The asymmetric unit of the title compound, bis[4,40
-methylenebis(3,5-dimethyl1H-pyrazol-2-ium)] -octamolybdate, (C11H18N4)2[Mo8O26] or
(H4mbdpz)2[Mo8O26], is composed of an H4mbdpz2+ cation and half of the
-octamolybdate anion which is completed by inversion symmetry. The organic
molecular units are engaged in a series of N—HO hydrogen bonds with
neighbouring anions, with NO distances and N—HO angles in the ranges
2.730 (2)–2.941 (2) A˚ and 122–166, respectively. These interactions lead to the
formation of a supramolecular two-dimensional network parallel to the (010)
plane
