摘要：
The new polydentate, pyridine-based phosphine ligand 2-(diphenylphosphino)-6-[3-(2'-pyridyl)-1-yl]-pyridine (L-2) has been synthesized. The reaction of L-2 With [Ag(MeCN)(4)][ClO4] resulted in the formation of the binuclear silver(I) complex [Ag-2(mu-L-2)(2)(ClO4)(2)], which is stabilized by significant pi-pi stacking interactions between its inter-ligand pyridyl fragments. In contrast, the reaction of 2-(diphenyiphosphino)-6-(pyrazol-1-yl)pyridine (L-1) with [Ag(MeCN)(4)][ClO4] gave the binuclear complex [Ag-2(mu-L-1)(2)(MeCN)(2)][ClO4](2), which exhibits a weak metal-metal interaction.
