Poly[(μ-β-hexacosaoxidooctamolybdato)tetrakis[3-(2-pyridyl)pyrazole]dizinc(II)]

In the hydrothermally prepared title compound, [Mo(8)Zn(2)O(26)(C(8)H(7)N(3))(4)] (n) or {[Zn(C(8)H(7)N(3))(2)](2)(Mo(8)O(26))} (n) , the ZnII atom is coordinated by two N,N'-bidentate 3-(2-pyridyl)pyrazole ligands and two O atoms from adjacent octamolybdate polyanions, generating a distorted cis-ZnO(2)N(4) octahedral geometry for the divalent metal ion. The complete octamolbydate unit is generated by crystallographic inversion symmetry. The polyhedral connectivity leads to [100] chains in the crystal and N-H...O and N-H...(O,O) hydrogen bonds help to consolidate the packing.
