Abstract:

1,2-Dicarba-closo-dodecaborane12 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-C5H5Mpi-B10C2H12 M FeIII and CoIII, pi-B10C2H122M-n M CoIII, FeII, and NiII, and pi-B10C2H12MCO3-2 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.
