The compounds Tl2, , 1-Ph-2-Me-3,3-L2-3,1,2-PtC2B9H9 have been prepared and characterised.The platinum complexes were obtained from the reactions between Tl2 and the appropriate species.Crystallographic studies upon the compounds where L = PEt3 and two crystalline modifications of that where L = PPh3 afforded evidance of a substantial influence of intramolecular crowding upon the observed structures, so that the lateral slippage (Δ) of the metal fragment is significantly enhanced: Δ = 0.74 and 0.94 and 0.91 Angstroem respectively.These compounds do not isomerise under conditions which produce rearrangement in the corresponding (less-congested) derivatives of 1-phenylcarbaborane, consistent with the proposed conformational destabilisation in the latter system.
