A Unifying Electron-Counting Rule for Macropolyhedral Boranes, Metallaboranes, and Metallocenes
TL;DR: A generally applicable electron-counting rule-the mno rule-that integrates macropolyhedral boranes, metallaboranes, and metallocenes and any combination thereof is presented and it is demonstrated that the number of skeletal bonding molecular orbitals of two polyhedral fragments remains unaltered during exohedral interactions.

Metal promoted charge and hapticities of phosphines: The uniqueness of carboranylphosphines
TL;DR: In this paper, the synergy effects between the o-carborane cluster and the P atom in these closo- and nido-Carboranylphosphines are observed from two points of view: the cluster and P atom.
