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

ABSTRACT: Crystals of the title compound, [Fe(C(8)H(7)N(3))(3)](2)[PMo(12)O(40)]·6H(2)O, prepared under hydro-thermal conditions, are isotypic with the Mn(2+) and Cd(2+) analogues. The Fe(2+) cation is in a distorted octa-hedral coordination by six N atoms from three chelating 3-(2-pyrid-yl)-1H-pyrazole ligands. The heteropoly-anion [PMo(12)O(40)](4-) is a one-electron reduced species in which 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 make a contribution to the crystal packing. The Fe-N bond lengths [2.085 (19)-2.15 (2) Å] are somewhat shorter than the Mn-N and Cd-N bond lengths [2.224 (6)-2.283 (5) and 2.316 (7)-2.334 (6) Å, respectively]. All other bond lengths and angles and the hydrogen-bonding motifs are v
