Abstract

Title full: Indenyl carbametallaboranes. III. The synthesis and characterization of novel rhodium carbaborane compounds with 3-(C₂B₉)-8-(C₉H₆)Rh(C₉H₇)-3,1,2-closo-RhC₂B₉, 10-(C₉H₆)Rh(C₉H₇)-7,8-nido-C ₂B₉, 9-(C₉H₆)Rh(C₉H₇)-7, 8-nido-C₂B₉ and 3-(η-C₉H₇)-3,1,2-closo-RhC₂B₉ structures. When RhCl₃·.3H₂O and indene are refluxed in methanol a brown solid, [(C₉H₇)RhCl₂]_x, is deposited. This, in turn, reacts with a suspension of Tl₂[7,8-nido-C₂B₉H₁₁ in CH₂Cl₂ to afford three products, 3-(C₂B₉H₁₁)-8-(C₉H₆)Rh(C₉H₇)-3,1,2-closo-RhC₂ B₉ H₁₀ (Ia), 10-(C₉H₆)Rh(C₉H₇)-7,8-nido-C ₂B₉H₁₁ (IIa) and 9-(C₉H₆) Rh(C₉H₇)-7,8-nido-C₂B₉H₁₁ (IIIa). In Ia, which was characterized spectroscopically and crystallographically, a closo-(C₂B₉H₁₁)Rh(C₂B₉H₁₀) fragment is bonded to a (C₉H₆)Rh(C₉H₇) fragment via a B(8)C bond, whereas in IIa and IIIa, which were characterized spectroscopically, the same organometallic fragment is linked to, respectively, B(10) and B(9) of a 7,8-nido-C₂B₉H₁₁ unit. Reaction of [(C₉H₇)RhCl₂]_x with Tl₂[7-(CH₂OCH₃)-7,8-nido-C₂B ₉H₁₀] gives rise to a single isolatable product of 7-CH₂OCH₃-10-(C₉H₆)Rh(C₉H₇)}-7, 8-nido-C₂B₉H₁₀ (IIb) shown to be a simple analogue of IIa by NMR spectroscopic study. An analogue of IIIa, namely 7-Ph-9/11-(C₉H₆)Rh(C₉H₇)-7,8 -nido-C₂ B₉H₁₀ (IIId) is one of the two products isolated following the reaction between [(C₉H₇) RhCl₂]_x and Tl₂[7-Ph-7,8-nido-C₂B₉H₁₀, the other being the closo carbametallaborane, 1-Ph-3-(C₉H₇)-3,1,2-closo-RhC₂B₉H₁₀ (IVd) characterized by unit cell and space group determination. A structural analogue, 1,2-(CH₂OCH₃)₂- 3-(C₉H₇)-3,1,2-closo-RhC₂B₉H ₉ (IVc) is the only product isolated from the reaction of [(C₉H₇)RhCl₂]_x with Tl₂[7,8-(CH₂OCH₃)₂-7,8-nido- C₂B₉H₉]. The structural characterization of each of these novel rhodium carbaborane species is discussed, and the implications of their structures on the nature of [(C₉H₇)RhCl₂]_x is considered.
