摘要

Anion effects on the formation of a cross-linked Ag-Ag interaction in the molecular construction of a series of AgX complexes with bis(3-pyridyl)dimethylsilane (L) (X~- = CF_3SO_3~-,PF_6~-,and NO_3~-) have been carried out.The slow diffusion of an organic solution of L into an aqueous solution of AgX afforded [Ag(L)]X or [Ag(X)(L)].Each L connected two Ag(I) ions (Ag-N = 2.110(5)-2.161(4) A) to form a wave strand.For CF_3SO_3~- and PF_6~- anions,each single strand cross-linked the adjacent single strands via an argentophilic interaction (Ag-Ag = 3.0551(7) A for CF_3SO_3~-,3.279(1) A for PF_6~-) to produce unique 2D sheets.In contrast,for the NO_3~- anion,the anion acts as a ligand (Ag-O_3N = 2.61-2.79 A) instead of the argentophilic interaction (Ag-Ag = 3.351(1) A).That is,a small coordinating anion is an obstacle to form the argentophilic interaction,whereas a big noncoordinating anion favors the argentophilic interaction in the present molecular construction.For all complexes,the geometry around the Ag(I) ion is a typical T-shaped arrangement.The thermal stability can be explained in terms of the structural properties,including the argentophilic interaction.
