In the title complex, [Zn2(C10H7NO6)2(C5H5N)2]n, the repeat unit is a centrosymmetic tetra-carboxylato-O,O'-bridged dimer in which each ZnII atom is five-coordinated by four O atoms from different dianionic 4,6-dimethyl-5-nitroisophthalate ligands [Zn-O = 2.0283 (18)-2.0540 (19) Å] and one N atom from a pyridine molecule [Zn-N = 2.030 (2) Å] in the axial site of a slightly distorted square-pyramidal coordination sphere. The ZnZn separation is 2.9750 (6) Å. The complex dimers are extended into a two-dimensional polymeric structure parallel to (100) through bridges provided by the second carboxylate group of the ligand.
