title: Poly[di-methyl-ammonium [(μ2-benzene-1,2-di-carboxyl-ato-κ(2) O (1):O (3))[μ2-3-(pyri-din-4-yl)-1H-pyrazol-1-ido-κ(2) N (1):N (3)]cuprate(II)]].
abstract: In the title complex, {(C2H8N)[Cu(C8H4O4)(C8H6N3)]} n , there are two Cu(II) cations (each located on a centre of inversion), one benzene-1,2-di-carboxyl-ate dianion, one 3-(pyridin-4-yl)-1H-pyrazol-1-ide anion and one di-methyl-ammonium cation in the asymmetric unit. The di-methyl-ammonium 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 Cu(II) cation exhibits a square-planar coordination geometry. A benzene-1,2-di-carboxyl-ate dianion bridges two Cu(II) 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 supra-molecular network through C-H⋯π inter-actions.
