Abstract: In the title compound, (C₂H₁₀N₂)[Cu(C₇H₃NO₄)₂(H₂O)₄]·2H₂O, the Cu^II ion occupies a special position on an inversion center and has an elongated octahedral geometry with the pyridine-3,5-dicarboxylate ligands in trans positions. The ethylenediammonium cation is also in a special position on an inversion center located at the mid-point of the C-C bond. Multiple crystallographically independent hydrogen bonds form a three-dimensional network in the crystal structure. - Interactions between aromatic rings of the pyridine-3,5-dicarboxylate ligand are observed. The electron-spin resonance (ESR) spectrum is in agreement with an elongated octahedral geometry.
