Popis: The hydrothermally prepared title compound, [Ni(C8H7N3)3]2[PMo12O40]·6H2O, is a member of the isotypic series [(M(C8H7N3)3]2[PMo12O40]·6H2O where M is Mn, Cd, and Fe. The Ni2+ cation is in a distorted octahedral environment, coordinated by six N atoms from three chelating 3-(2-pyridyl)-1H-pyrazole ligands. In the one-electron reduced 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 bonds contribute to the crystal packing. Compared with the isotypic structures, the main difference is related with the M—N bond lengths, whereas all other bond lengths, angles and the hydrogen-bonding motifs are very similar.
