Tetra-μ(3)-iodido-tetra-kis-{[ethyl 2-(1H-benzimidazol-1-yl)acetate-κN(3)]copper(I)}.
The complex mol-ecule of the tetra-nuclear cubane-type title compound, [Cu(4)I(4)(C(11)H(12)N(2)O(2))(4)], has crystallographically imposed fourfold inversion symmetry. The Cu(I) ions are coordinated in a distorted tetra-hedral geometry by an N atom of a benzimidazole ring system and three μ(3)-iodide ions, forming a Cu(4)I(4) core. In the crystal, complex mol-ecules are connected into a three-dimensional network by C-H⋯O hydrogen bonds involving H and O atoms of adjacent eth-oxy-carbonyl groups.
