Bis(μ-L-arginine-κ³N²,O:O′)bis­(L-arginine-κ²N²,O)tetra-μ-chlorido-tetra­chlorido­tetra­copper(II)

The title compound, [Cu₄Cl₈(C₆H₁₄N₄O₂)₄], contains four mol­ecules in the asymmetric unit. In the mol­ecular structure, each of the four Cu²⁺ ions binds to three Cl atoms, one N atom and one O atom, resulting in distorted square-pyramidal coordination environments. The molecular structure is stabilized by weak C—H...O and N—H...Cl hydrogen bonds. The crystal structure exhibit weak inter­molecular N—H...O, C—H...O and N—H...Cl inter­actions, generating a three-dimensional network.
