چکیده
The title compound, [Mn(C(8)H(7)N(3))(3)](2)[SiMo(12)O(40)]·6H(2)O, consists of an [SiMo(12)O(40)](4-) heteropolyanion, lying on a centre of inversion, and a complex [Mn(C(8)H(7)N(3))(3)](4+) cation. The Mn(II) atom of the cation is hexa-coordinated in a distorted octa-hedral geometry by six N atoms from three chelating 3-(2-pyrid-yl)pyrazole ligands. In the heteropolyanion, the four O atoms of the tetra-hedral SiO(4) group each half-occupy eight sites due to Si lying on the centre of inversion. N-H⋯O and O-H⋯O hydrogen bonding mediated by the water mol-ecules leads to a consolidation of the structure.
