Figure 4: Space-filling representations of SK-1A.
From: Ultra-large supramolecular coordination cages composed of endohedral Archimedean and Platonic bodies

The molecular structure is shown from two different perspectives (a,b); Colour code, blue C, red O-donor coordination in the {Cu2} units, white H, dark blue N; coordinating solvent molecules are shown in non space-filling representations.
