Novel 13-Vertex Metallocarborane Complexes Formed by Polyhedral Expansion of 1,2-B10C2H12.
Abstract
1,2-Dicarba-closo-dodecaborane(12) was found to undergo a two-electron reduction with sodium metal in tetrahydrofuran to form a B10C2H12 (-2) ion. This ion serves as a ligand in the formation of a variety of transition metal complexes which include ((pi-C5H5)M(pi-B10C2H12)) (M = Fe(III) and Co(III), ((pi-B10C2H12)2M')(-n) (M' = Co(III), Fe(II), and Ni(II)), and ((pi-B10C2H12)M''(CO)3)(-2) (M'' = Mo and W). The preparation, characterization, and structures of these complexes are discussed. In each case, a closo-polyhedral structure is proposed with the metal atom located at one of the 13 vertices.
