Figure 2
The coordination environment of atom Cu3 in (1), showing its CuOCl3 tetrahedron (solid lines for Cu—O and Cu—Cl bonds and open lines connecting vertices) and dashed lines indicating short Cu⋯Cu contacts to Cu4 (`semi-supported' via the bridging –CO2 group) and Cu8 (unsupported); note how these pass through the tetrahedral faces.
