Poly[(μ(3)-quinoline-6-carboxyl-ato-κ(3)N:O:O')silver(I)]

Abstract

In the title coordination polymer, [Ag(C(10)H(6)NO(2))](n), the Ag(I) cation is coordinated by two O atoms and one N atom from three 6-quinoline-carboxyl-ate anions in a distorted T-shaped AgNO(2) geometry, in which the O-Ag-O angle is 160.44 (9)°. The 6-quinoline-carboxyl-ate anion bridges three Ag(+) cations, forming a nearly planar polymeric sheet parallel to (101). The distance between Ag(+) cations bridged by the carboxyl group is 2.9200 (5) Å. In the crystal, π-π stacking is observed between parallel quinoline ring systems, the centroid-centroid distance being 3.7735 (16) Å.
