Abstract

The first metallocarborane complex, [3,3’-FeII(l,2-C2B9H11)2]21 the carborane analog of ferrocene, was first synthesized ten years ago. This compound bridged boron hydride and carborane chemistry with that of the transition metals, and heralded the explosive proliferation of metallocarborane chemistry.

    A closo-boron hydride (BnHn2-, x=n), carborane (C2BnHn+2, x=n+2), or metallocarborane (LC2BnHn+2, x=m+n+2 where M is a metal and L a ligand), containing x skeletal atoms, assumes a structure in which all x vertices of an exclusively triangular-faced polyhedron (Figure 3) are occupied. A nido-compound containing x skeletal atoms occupies all but one vertex of the polyhedron containing x+1 vertices.Google Scholar
