Bis{tris-[3-(2-pyrid-yl)-1H-pyrazole]zinc(II)} dodeca-molybdosilicate hexa-hydrate.


ABSTRACT: The asymmetric unit of the title compound, [Zn(C(8)H(7)N(3))(3)](2)[SiMo(12)O(40)]·6H(2)O, consists of a complex [Zn(C(8)H(7)N(3))(3)](2+) cation, half of a Keggin-type [SiMo(12)O(40)](4-) heteropolyanion and three uncoordinated water mol-ecules. The Zn(2+) cation is surrounded in a distorted octa-hedral coordination by six N atoms from three chelating 3-(2-pyrid-yl)pyrazole ligands. In the heteropolyanion, two O atoms of the central SiO(4) group ( symmetry) are equally disordered about an inversion centre. N-H?O hydrogen bonding between the cations, anions and the uncoordinated water mol-ecules leads to a consolidation of the structure.
