The title compound, (C6H9N2)2[Cu(C6H2N2O4)2(H2O)2]- 6H2O, consists of a mononuclear trans-[Cu(pzdc)2(H2O)2]2 dianion (pzdc is pyrazine-2,3-dicarboxylate) and two [ampyH]+ cations (ampy is 2-amino-4-methylpyridine) with six water molecules of solvation. The CuII atom is hexacoordinated by two pzdc groups and two water molecules. The coordinated water molecules are in trans-diaxial positions and the pzdc dianion acts as a bidentate ligand through an O atom of the carboxylate group and the N atom of the pyrazine ring. There are diverse hydrogen-bonding interactions, such as N— H  O and O—H  O contacts, which lead to the formation of a three-dimensional supramolecular architecture.
