Abstrakt: A reaction of iodide [(η-indenyl)IrI] ( 1) with thallium dicarbollide Tl[Tl(η-7,8-CBH)] leads to (indenyl)iridacarborane (η-indenyl)Ir(η-7,8-CBH) ( 2) in 32% yield. The X-ray diffraction study showed that in the structure of 2, the five-membered rings C and CB have a cisoid conformation, in which the bridgehead carbon atoms of the indenyl ligand are arranged opposite to the carborane cage carbon atoms. The DFT calculations showed that the Ir-indenyl bond in compound 2 is weaker than the Ir-Cp bond in the complex (η-7,8-CBH)IrCp. [ABSTRACT FROM AUTHOR]
