Abstract:

Abstraction of bridging protons from B10CH13- with ethanolic KOH followed by addition of C5H6 and anhydrous CoCl2 and subsequent oxidation produces a high yield of the eta-C5H5CoIIIeta-7-B10CH11- ion. Abstraction of NCH33 and bridging protons from B10H12CNCH33 with sodium in THF followed by the addition of NaC5H5 and NiBr2-2C2H4OCH32 and subsequent oxidation gives a low yield of eta-C5H5NiIVeta-7-B10CH11. Both metallocarboranes are isoelectronic and isostructural with the icosahedral two carbon species, eta-C5H5CoIIIeta-B9C2H11, and contain the metal atom bonded to a B4C face. At 450C under high vacuum eta-C5H5NiIVeta-7-B10CH11 rearranges to a mixture of eta-C5H5NiIVeta-2-B10CH11 and eta-C5H5NiIV-eta-1-B10CH11. Author
