title: catena-Poly[[[aqua-silver(I)]-μ-1,1'-(butane-1,4-di-yl)di-1H-imidazole-κN:N] hemi(biphenyl-4,4'-dicarboxyl-ate) dihydrate].
abstract: In the title compound, {[Ag(C(10)H(14)N(4))(H(2)O)](C(14)H(8)O(4))(0.5)·2H(2)O}(n), the Ag(I) ion is three-coordinated by two N atoms from two independent 1,1'-(butane-1,4-di-yl)di-1H-imidazole (BBI) ligands and one water O atom in a distorted T-shaped coordination geometry. The biphenyl-4,4'-dicarboxyl-ate (BPDC) dianions do not coordinate to Ag(I) ions but act as counter-ions. The Ag(I) ions are linked by BBI ligands, forming a zigzag chain. These chains are linked into a two-dimensional supra-molecular architecture by O-H⋯O hydrogen-bonding inter-actions between water mol-ecules and carboxyl-ate O atoms of the BPDC dianions.
