Di‐μ‐chloro‐1:2κ2Cl;3:4κ2Cl‐hexachloro‐1κ3Cl,4κ3Cl‐tetra‐μ‐dimethyl­glycine‐2:3κ8O:O′‐tetra­copper(II)

The title compound, Cu₄Cl₈(C₄H₉NO₂)₄], crystallizes in the centrosymmetric space group P2₁/c with a unit cell containing two tetra­nuclear copper(II) complexes sited on crystallographic inversion centres. The coordination geometry around the central Cu atoms is square pyramidal, with four O atoms in the basal plane and a Cl atom in the apical position. The lateral CuCl₄ groups are flattened tetra­hedral. The bridging dimethyl­glycine mol­ecules are present in the dipolar zwitterionic form. The tetra­nuclear copper complexes exist as isolated entities since only intra­molecular hydrogen bonds are found.
