Abstract

The new polydentate, pyridine-based phosphine ligand 2-(diphenylphosphino)-6-[3-(2′-pyridyl)-pyrazol-1-yl]pyridine (L2) has been synthesized. The reaction of L2 with [Ag(MeCN)4][ClO4] resulted in the formation of the binuclear silver(I) complex [Ag2(µ-L2)2(ClO4)2], which is stabilized by significant π–π stacking interactions between its inter-ligand pyridyl fragments. In contrast, the reaction of 2-(diphenylphosphino)-6-(pyrazol-1-yl)pyridine (L1) with [Ag(MeCN)4][ClO4] gave the binuclear complex [Ag2(µ-L1)2(MeCN)2][ClO4]2, which exhibits a weak metal–metal interaction.
