Abstract
The hydrothermally prepared title compound, [Ni(C8H7N3)(3)](2)[PMo12O40]center dot 6H(2)O, is a member of the isotypic series [(M(C8H7N3)(3)](2)[PMo12O40]center dot 6H(2)O 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 (1 symmetry) are equally disordered about an inversion centre. N-H center dot center dot center dot O and O-H center dot center dot center dot 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 hydrogenbonding motifs are very similar.Keywords
