Figure 2
(a) The core of the cubane unit, which sits on a site of [\overline{4}] symmetry. Only the unique citrate ligand is shown. Displacement ellipsoids are drawn at the 50% probability level. (b) The full [Co4(citrate)4]8− `cubane', showing the five- and six-membered chelates (in the electronic version of the paper, these are in pink and aqua­marine, respectively). H atoms have been omitted for clarity. [Symmetry codes: (i) −x + 1, −y + 1, z; (ii) −y + 1, x, −z + 1; (iii) y, −x + 1, −z + 1.]
