Abstract
In the title compound, (C2H10N2)[Zn(C2H8N2)2(H2O)2][Zn(C7H3NO4)2]2·2H2O, the Zn atom (site symmetry 2/m) in the [Zn(C2H8N2)2(H2O)2]2+ cation is six-coordinated by four N atoms from bidentate ethylenediammonium molecules and two water O atoms. The Zn atom (site symmetry 2) in the [Zn(C7H3NO4)2]2− anion is six-coordinated by four O atoms and two N atoms from two tridentate pyridine-2,6-dicarboxylate ligands. An uncoordinated ethylenediammonium cation and two water molecules are also present in the structure. The crystal packing is stabilized by O—H⋯O and N—H⋯O hydrogen bonds, forming a three-dimensional network.
