Abstract: The title compound, [Cu₂(C₇H₃NO₄)₂(C₇H₈N₄)(H₂O)₂]·4H₂O, has a dinuclear structure in which each Cu^II atom is five-coordinate in a distorted square-based pyramidal geometry and the 1,1'-methylenedi-1H-imidazole ligand adopts a bis-monodentate bridging mode, linking the Cu^II atoms. A twofold rotation axis passes through the C atom linking the imidazole rings. The molecules are connected by O-HO hydrogen bonds [OO = 2.748 (3)-2.973 (3) Å].
