In the title compound two C‐atoms are located in the cavity of a cluster . The CċC distance in very short—only 1.49 Å (for comparison: CC single bond 1.54 Å)—but, as deduced from a consideration of the number of cluster valence electrons, a delocalized CC interaction is more probable than a localized one.
