Q. Li, R. Zhang and Y. Shi

Abstract: In the title compound, C₂₀H₂₄N₂O₄, the molecule lies on a centre of symmetry and is approximately planar (r.m.s. deviation= 0.013 Å for 26 non-H atoms). The carboxylate group is inclined slightly to the neighbouring pyridine ring, forming a dihedral angle of 4.37 (2)°. The molecules form stacks with an interplanar separation of 3.547 (1) Å.
