The asymmetric unit of the title compound, [Mn(C(8)H(7)N(3))(3)](2)[PMo(12)O(40)]·6H(2)O, consists of a complex [Mn(C(8)H(7)N(3))(3)](2+) cation, half of a mixed-valent Mo(V,VI) α-Keggin-type [PMo(12)O(40)](4-) heteropolyanion, and three uncoordinated water mol-ecules. The Mn(2+) cation is surrounded by six N atoms from three chelating 3-(2-pyrid-yl)-1H-pyrazole ligands in a distorted octa-hedral coordination. In the heteropolyanion, two O atoms of the central PO(4) group ( 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 mol-ecules leads to a consolidation of the structure.
