In the title compound, [Ag(BF(4))(C(14)H(12)N(2)O(4))](n), the coordination of the Ag(+) ion is trigonal-bipyramidal with the N atoms of two ethane-1,2-diyl bis-(pyridine-3-carboxyl-ate) ligands in the apical positions and three F atoms belonging to different tetra-fluorido-borate anions in the equatorial plane. The material consists of infinite chains of [Ag(C(14)H(12)N(2)O(4))] units running along [001], held together by BF(4) (-) bridging anions.
