| Summary: | The asymmetric unit of the title compound, [Mn(C8H7N3)3]2[PMo12O40]·6H2O, consists of a complex [Mn(C8H7N3)3]2+ cation, half of a mixed-valent MoV,VI α-Keggin-type [PMo12O40]4− heteropolyanion, and three uncoordinated water molecules. The Mn2+ cation is surrounded by six N atoms from three chelating 3-(2-pyridyl)-1H-pyrazole ligands in a distorted octahedral coordination. In the heteropolyanion, two O atoms of the central PO4 group (overline{1} symmetry) are equally disordered about an inversion centre. N—H...O and O—H...O hydrogen bonding between the cations, anions and the uncoordinated water molecules leads to a consolidation of the structure.
