Abstract

Title full: Steric effects in heteroboranes. Part 7¹ 1 For Part 6, see Ref. [1]. The synthesis and characterisation of arene-ruthenium complexes of C-substituted carbaboranes. Molecular structures of 1-Ph-3-(mes)-3,1,2-closo-RuC₂B₉H₁₀ (mes = C₆H₃-1,3,5) and 1-Ph-2-Me-3-(p-cym)-3,1,2-closo-RuC₂B₉H₉ (p-cym = C₆H₄Me-1-ⁱPr-4), the latter showing an incipient deformation. The synthesis and characterization of Tl₂[7-Ph-7,8-nido-C₂B₉H₁₀], 3-(p-cym)-3,1,2-closo-RuC₂B₉H₁₀ (1), 1-Ph-3-(mes)-3,1,2-closo-RuC₂B₉H₁₀ (2), 1-Ph-3-(P-cym)-3,1,2-closo-RuC₂B₉H₁₀ (3) and 1-Ph-2-Me-3-(p-cym)-3,1,2-closo-RuC₂B₉H₉ (4) are reported. The ruthenium-containing species are obtained from the reactions between the appropriate [(arene)RuCl₂]₂ and either Tl₂[7,8-nido-C₂B₉H₁₁], Tl₂[7-Ph-7,8-nido-C₂B₉H₁₀] or Tl₂[7-Ph-8-Me-7,8-nido-C₂B₉HP₉]. Crystallographic studies on 2 and 4 reveal that whereas the former contains an essentially undistorted {RuC₂B₉} framework, there is some indication that in the latter, a polyhedral deformation from closo towards pseudocloso has just begun. This idea gains support from comparison of the ¹¹B NMR shifts for 1, 3 and 4 with those for reference carbaboranes.
