- Poly[[μ-ethane-1,2-diyl bis-(pyridine-3-carboxyl-ate)](μ-tetra-fluorido-borato)silver(I)] (2012)
- In the title compound, [Ag(BF4)(C14H12N2O4)]n, the coordination of the Ag+ ion is trigonal–bipyramidal with the N atoms of two ethane-1,2-diyl bis(pyridine-3-carboxylate) ligands in the apical positions and three F atoms belonging to different tetrafluoridoborate anions in the equatorial plane. The material consists of infinite chains of [Ag(C14H12N2O4)] units running along , held together by BF4 − bridging anions.
- Butane-1,4-diyl bis-(pyridine-3-carboxyl-ate) (2012)
- Molecules of the title compound (alternative name: butane-1,4-diyl dinicotinate), C16H16N2O4, lie on a inversion centre, located at the mid-point of the central C—C bond of the aliphatic chain, giving one half-molecule per asymmetric unit. The butane chain adopts an all-trans conformation. The dihedral angle between the mean plane of the butane-3-carboxylate group [for the non-H atoms, maximum deviation = 0.0871 (15) Å] and the pyridine ring is 10.83 (7)°. In the crystal, molecules lie in planes parallel to (122). The structure features weak π–π interactions with a centroid–centroid distance of 3.9281 (11) Å.
