Crystal and molecular structure of nitrato(6,6′-dimethyl-2,2′-bipyridine)silver(I). A dimer held by stacking and silver-silver interactions (original) (raw)

The crystal and molecular structure of Ag(dmbp)NO3, where dmbp=6,6'-dimethyl-2,2'-bipyridine, has been determined. The crystal consists of dimers formed by two symmetry-related molecules. Each dimerie unit is held together by (weak) Ag-Ag and heteroaromatic ring stacking interactions. Stacking interactions lead to a slipped stack arrangement of the dimers. The coordination around silver is very nearly planar (tetrahedral distortion angle = 15~ with the nitrate ion acting as an unsymmetrical chelating ligand.
