catena-Poly[[(di-2-pyridylamine-κ2 N, N′)copper(II)]-μ-benzene-1,4-dicarboxyl­ato-κ4 O, O′: O′′, O′′′].

In the title complex, [Cu(C8H4O4)(C10H9N3)] n, the benzene-1,4-dicarboxyl­ate dianions bridge the CuII atoms to form polymeric complex chains. The CuII atom has a distorted octa­hedral coordination geometry. The centroid-to-centroid separation of 3.932 (2) Å indicates π–π stacking between nearly parallel pyridine rings.
