摘要The reaction of 2,6-pyridinediylbis(3-pyridinyl)methanone (abbreviated as L) with various silver(I) salts yielded a series of complexes, namely, [Ag-2(L)(2)](ClO4)(2) (1), {[Ag-2(L)(2)](ClO4)(2)} (2), {[Ag-2(L)(2)](NO3)(2)} (3), {[Ag-2(L)(2)](C2F5CO2)(2)} (4), {[Ag-2(L)(2)](C3F7CO2)(2)} (5), and {[Ag-2(L)(2)](O2CC3F6CO2)2H(2)O} (6), which exhibit a common dinuclear metallacyclic [Ag-2(L)(2)](2+) skeleton that involves linear-dicoordinate Ag-I and (2)-N,N-bridging L. Complex 2 is a polymorph of 1 obtained by the solvent-medium tuning effect, and it has an {[Ag-2(L)(2)](2+)} infinite-chain structure. In complexes 3-6, the argentophilic interaction plays an important role in connecting the [Ag-2(L)(2)](2+) units to form a similar {[Ag-2(L)(2)](2+)} chain structure to that in 2, although the counteranions are markedly different. The copper(II) complex {[Cu-2(CH3CO2)(4)(L)]2H(2)O} (7) exhibits a zigzag-chain structure composed of an alternating arrangement of L and the Cu-2(CH3CO2)(4) paddlewheel cluster. In the supramolecular architectures of 1-7, the counteranions engage in multiple noncovalent interactions, and the presence of unusual types such as O/F(anion), O/F(anion)C=O, and C=O are noted and discussed.
