The complex molecule of the tetranuclear cubane-type title compound, [Cu4I4(C11H12N2O2)4], has crystallographically imposed fourfold inversion symmetry. The CuI ions are coordinated in a distorted tetrahedral geometry by an N atom of a benzimidazole ring system and three μ3-iodide ions, forming a Cu4I4 core. In the crystal, complex molecules are connected into a three-dimensional network by C—H⋯O hydrogen bonds involving H and O atoms of adjacent ethoxycarbonyl groups.
