摘要

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.
