In the title compound, [Cu2(SO4)2(C20H36N8)(H2O)2]·6H2O, the dinuclear molecule lies across an inversion centre and contains square-pyramidal CuII ions separated by 7.5709 (18) Å. Symmetry-related molecules are linked together by hydrogen bonds between the coordinated water molecules and the sulfate ligands. They are further linked by a framework of fused cyclic water tetrameric and pseudo-hexagonal units in a three-dimensional hydrogen-bonded network involving both coordinated and uncoordinated water molecules, as well as sulfate ligands. While the tetrameric units are purely composed of water molecules, the pseudo-hexagonal units involve O atoms from the sulfate. Further hydrogen bonding also involves the NH group from the imidazole in addition to the above-mentioned units.
