A novel one-dimensional metal-organic framework with a μ-cyanido-argentate group: catena-poly[[(5,5'-dimethyl-2,2'-bipyridyl-κ(2)N,N')silver(I)]-μ-cyanido-κ(2)N:C].

The design and synthesis of metal coordination and supra­molecular frameworks containing N-donor ligands and dicyanidoargentate units is of inter­est due to their potential applications in the fields of mol­ecular magnetism, catalysis, nonlinear optics and luminescence. In the design and synthesis of extended frameworks, supra­molecular inter­actions, such as hydrogen bonding, π–π stacking and van der Waals inter­actions, have been exploited for mol­ecular recognition associated with biological activity and for the engineering of mol­ecular solids.The title compound, [Ag(CN)(C12H12N2)]n, crystallizes with the AgI cation on a twofold axis, half a cyanide ligand disordered about a centre of inversion and half a twofold-symmetric 5,5′-dimethyl-2,2′-bipyridine (5,5′-dmbpy) ligand in the asymmetric unit. Each AgI cation exhibits a distorted tetra­hedral geometry; the coordination environment comprises one C(N) atom and one N(C) atom from substitutionally disordered cyanide bridging ligands, and two N atoms from a bidentate chelating 5,5′-dmbpy ligand. The cyanide ligand links adjacent AgI cations to generate a one-dimensional zigzag chain. These chains are linked together via weak nonclassical inter­molecular inter­actions, generating a two-dimensional supra­molecular network.
