title: Poly[[bis-(nitrato-κO)bis-(μ(4)-pyridine-4-carboxyl-ato)tetra-kis-(μ(3)-pyridine-4-carboxyl-ato)octa-silver(I)] hemihydrate].
abstract: In the title coordination polymer, {[Ag(8)(C(6)H(4)NO(2))(6)(NO(3))(2)]·0.5H(2)O}(n), two Ag(I) ions are two-coordinate within an AgN(2) set and six are three-coordinate within AgN(2)O and AgO(3) sets. The Ag-N and Ag-O distances are in the ranges 2.150 (5)-2.198 (5) and 2.142 (4)-2.702 (5) Å, respectively. A two-dimensional coordination network is formed parallel to (100). The O atom of the disordered solvent water mol-ecule is located on an inversion center.
