چکیده
The hydro-thermally prepared title compound, [Ni(C(8)H(7)N(3))(3)](2)[PMo(12)O(40)]·6H(2)O, is a member of the isotypic series [(M(C(8)H(7)N(3))(3)](2)[PMo(12)O(40)]·6H(2)O where M is Mn, Cd, and Fe. The Ni(2+) cation is in a distorted octa-hedral environment, coordinated by six N atoms from three chelating 3-(2-pyrid-yl)-1H-pyrazole ligands. In the one-electron reduced 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 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.
