“The preparative exploration of ever more shallow potential troughs” is facilitating the synthesis of supramolecular complexes with increasing “storybook” character. Reduction of Ph 2 C CPh 2 under argon using a sodium mirror and diethyl ether results in green crystals with metallic luster and a novel band structure. A single C 2 Ph 4 segment is shown on the right, the view being one that clearly reveals the rotation of one half of the molecule relative to the other.
