Bis{tris-[3-(2-pyrid-yl)-1H-pyrazole]cadmium(II)} dodeca-molybdo(V,VI)phosphate hexa-hydrate.


ABSTRACT: The hydro-thermally 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 octa-hedral environment, coordinated by six N atoms from three chelating 3-(2-pyrid-yl)-1H-pyrazole ligands. In the 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 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.
