A number of (hetero)boranes are known in which a main group atom X ‘bridges’ a B—B connectivity in the open face, and in such species X has previously been described as simply a bridge or, alternatively, as a vertex in a larger cluster. In this

The molecular structure of the title compound 1-(2′,3′,5′,6′-tetrafluoro-4′-trifluoromethylphenyl)-closo-1,2-dicarbadodecaborane, C9H11B10F7, features an intramolecular ortho-F...H2 hydrogen bond [2.11 (2) Å], which is responsible for an o

We report herein the first example of the controlled isomerisation of a C,Cʹ-bound (to metal) bis(ortho-carborane) ligand to C,Bʹ-bound with no other change in the molecule. Since the C and B vertices of carboranes have different electron-donating

In the title compound, C4H22B20, the two {1,2-closo-C2B10H11} cages are linked across a centre of inversion with a C—C distance of 1.5339 (11) Å. By careful analysis of the structure, it is established that the non-linking cage C atom is equally d

Dehalogenation of[1,2-Ph2-3,3-(PPh3)2-3-Cl-closo/pseudocloso-3,1,2-RuC2B9H9]− affords, in addition to the unusual “symbiotic”** cluster [(1,2-Ph2-pseudocloso-3,1,2-RuC2B9H9) (1′,8′-Ph2-closo-2′,1′8′-RuC2B9H9)], a trace amount of a tri

Deprotonation of [7-(1'-closo-1',2'-C2B10H11)-nido-7,8-C2B9H11]- and reaction with [Rh(PPh3)3Cl] results in isomerization of the metalated cage and the formation of [8-(1'-closo-1',2'-C2B10H11)-2-H-2,2-(PPh3)2-closo-2,1,8-RhC2B9H10] (1). Similarly, d
