In the polymeric title complex, [Zn(C9H7NO4)]n, the ZnII cation is located on a twofold rotation axis and is coordinated by five 2,6-dimethylpyridine-3,5-dicarboxylate (mpdc) anions in a distorted ZnNO4 trigonal–bipyramidal geometry. The mpdc anion is also located on the twofold rotation axis and bridges five ZnII cations, forming the three-dimensional polymeric complex. Weak C—H⋯π interactions are present in the crystal structure.
