Abstract

A dinuclear silver(I) com-plex of 6-phenyl-2,2':6',2''-terpyridine, bis-(μ-6-phenyl-2,2':6',2''-terpyridine)-bis-[(tri-fluoro-methane-sulfonato)-silver(I)], [Ag2(C21H15N3)(CF3SO3)2], was obtained by crystallization with silver tri-fluoro-methane-sulfonate and characterized by single-crystal X-ray diffraction. Two symmetry-related terpyridine ligands bridge two AgI ions. The AgI ion has a highly distorted four-coordinate N3O environment com-prising three pyridyl N atoms and one tri-fluoro-methane-sulfonate O atom. The intra-molecular Ag⋯Ag separation of 2.8501 (8) Å is consistent with an argentophilic inter-action. An intra-molecular phen-yl-pyridyl π-π contact is also present. The structure demonstrates that a single phenyl substituent at the 6-position is com-patible with ligand bridging and the formation of a short Ag⋯Ag contact.
