Abstract: In the title complex, {(C2H8N)[Cu(C8H4O4)(C8H6N3)]}n, there are two CuII cations (each located on a centre of inversion), one benzene-1,2-dicarboxylate dianion, one 3-(pyridin-4-yl)-1H-pyrazol-1-ide anion and one dimethylammonium cation in the asymmetric unit. The dimethylammonium cation was highly disordered and was treated with the SQUEEZE routine in PLATON [Spek (2009). Acta Cryst. D65, 148-155]; the crystallographic data takes into account the presence of the cation. Each CuII cation exhibits a square-planar coordination geometry. A benzene-1,2-dicarboxylate dianion bridges two CuII cations, building a linear chain along [001]. The chains are connected by 3-(pyridin-4-yl)-1H-pyrazol-1-ide anions, constructing a layer parallel to (101). The layers are assembled into a three-dimensional supramolecular network through C-H...[pi] interactions.
