Abstract

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 = 0.0871 (15) Å] and the pyridine ring is 10.83 (7)°. In the crystal, mol-ecules lie in planes parallel to (122). The structure features weak π-π inter-actions with a centroid-centroid distance of 3.9281 (11) Å.
