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

Abstract

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 dimeric 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. © 1992 Chapman & Hall.
