The title compound, C(15)H(14)N(2)O(4), has a trans-gauche [O/C/C/C-O/C/C/C] (TG) conformation. The angle between the planes of aromatic rings is 76.4 (3)°. The crystal structure is stabilized by van der Waals inter-actions and C-H⋯O hydrogen bonds. The crystal used was a non-merohedral twin with a fractional contribution of the minor component of 0.443 (5).

Mol-ecules of the title compound (alternative name: butane-1,4-diyl dinicotinate), C(16)H(16)N(2)O(4), lie on a inversion centre, located at the mid-point of the central C-C bond of the aliphatic chain, giving one half-mol-ecule per asymmetric unit. The butane chain adopts an all-trans conformation. The dihedral angle between the mean plane of the butane-3-carboxyl-ate group [for the non-H atoms, maximum deviation = 0.

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.
