Compound 2 adopts a perfectly symmetrical 10-vertex-nido framework with a plane of symmetry bisecting the basal boron plane resulting in two {CoB3} units bridged at the base by two boron atoms and possesses the expected electron count.

Hence they have arachno-like structures, although they have only n + 1 (n = 7) electron pairs: again the PSEPT rules are violated.All of these structures are characterized by the locations of two bridged bonds; one is at the same …
