Sumario:The hydro­thermally prepared title compound, [Cd(C(8)H(7)N(3))(3)](2)[PMo(12)O(40)]·6H(2)O, is isotypic with its Mn(II) analogue [Hao et al. (2010 ▶). Acta Cryst. E66, m231–m232]. The Cd(II) cation is in a distorted octa­hedral environment, coordinated by six N atoms from three chelating 3-(2-pyrid­yl)-1H-pyrazole ligands. In the reduced heteropolyanion, two O atoms of the central PO(4) group ([Image: see text] 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 Mn(II) analogue, the Cd—N bond lengths are longer at 2.316 (7)–2.334 (6) Å, versus 2.224 (6)–2.283 (5) Å for Mn—N, whereas all other bond lengths and angles and the hydrogen-bonding motifs are very similar in the two structures.
