Diaquabis(4-carboxy-2-propyl-1H-imidazole-5-carboxylato-κ2N3,O4)copper(II) N,N-dimethylformamide disolvate

In the title complex, [Cu(C8H9N2O4)2(H2O)2]·2C3H7NO, the CuII ion, lying on an inversion center, is six-coordinated in a slightly distorted octahedral geometry. Two N atoms and two O atoms from two H2pimda (H3pimda is 2-propyl-1H-4,5-dicarboxylic acid) ligands are in the equatorial plane. The axial positions are occupied by two O atoms from two water molecules. A two-dimensional supramolecular network parallel to (001) is constructed by N—H...O and O—H...O hydrogen bonds. An intramolecular O—H...O hydrogen bond is also observed.
