catena-Poly[[bis­(1,3-propyl­enediamine)zinc(II)]-μ-naphthalene-2,6-dicarboxyl­ato-κ2 O2: O6].

The title compound, [Zn(C12H6O4)(C3H10N2)2] n, has been prepared from zinc(II), naphthalene-2,6-dicarboxylic acid (H2napdc) and 1,3-propyl­enediamine (pren). The Zn atom lies on a crystallographic centre of symmetry and is coordinated by two monodentate naphthalene-2,6-dicarboxyl­ate ligands and two chelating 1,3-propyl­enediamine ligands in a distorted octa­hedral environment. The naphthalene-2,6-dicarboxyl­ate ligands link the Zn atoms, forming a one-dimensional chain structure. [ABSTRACT FROM AUTHOR]
