Bis(μ-l-arginine-κ(3) N (2),O:O′)bis­(l-arginine-κ(2) N (2),O)tetra-μ-chlorido-tetra­chlorido­tetra­copper(II)

The title compound, [Cu(4)Cl(8)(C(6)H(14)N(4)O(2))(4)], contains four mol­ecules in the asymmetric unit. In the mol­ecular structure, each of the four Cu(2+) 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.
