title: Poly[(μ(2)-2,2'-bipyridine-κN:N')bis-(μ(3)-2,2,2-trifluoro-acetato-κO:O:O')disilver(I)].
abstract: In the title salt, [Ag(2)(CF(3)CO(2))(2)(C(10)H(8)N(2))](n), which may also be regarded as a coordination polymer if long Ag⋯O inter-actions are considered, each of the N atoms of the somewhat twisted 2,2'-bipyridine mol-ecule [N-C-C-N = -27.5 (4)°] binds to an Ag atom, and each of the carboxyl-ate ligands is tridentate, linking to three Ag atoms. The bidentate carboxyl-ate O atoms bridge the same two Ag atoms, resulting in the formation of Ag(2)O(2) 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 NO(4) 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 inter-actions.
