Poly[(μ₂-2,2′-bipyridine-κ²N:N′)bis(μ₃-2,2,2-trifluoroacetato-κ³O:O:O′)disilver(I)]

Abstract

In the title salt, [Ag2(CF3CO2)2(C10H8N2)]n, which may also be regarded as a coordination polymer if long Ag⋯O inter­actions are considered, each of the N atoms of the somewhat twisted 2,2′-bipyridine mol­ecule [N—C—C—N = −27.5 (4)°] binds to an Ag atom, and each of the carboxyl­ate ligands is tridentate, linking to three Ag atoms. The bidentate carboxyl­ate O atoms bridge the same two Ag atoms, resulting in the formation of Ag2O2 rings. These rings are bridged by the 2,2′-bipyridine ligands, forming a chain along the b axis. The chains are linked into double chains via the remaining Ag—O bonds and Ag⋯Ag contacts. As a consequence of the Ag⋯Ag contacts, the NO4 donor set about each Ag atom is heavily distorted. Finally, the chains are linked into a three-dimensional network by a combination of C—H⋯O and C—H⋯F inter­actions.
