of [Cp*IrB4H10] (1) with [η6-(C6H4)(CH3)2}Mo(CO)3] in tetrahydrofuran (THF) leads to [Cp*Ir(CO)3(THF)MoB4H8] (2), which was characterized by NMR spectroscopy. Intermediate 2 subsequently decomposes to give the tetracarbonyl analogue [Cp*Ir(CO)4MoB4H8] (3). In the presence of free CO, the same reaction constitutes a high-yield synthesis of 3. The treatment of 2 (formed in situ) with different Lewis bases

The three (eta(6)-xylene)Mo(CO)(3) complexes have been prepared and crystallographically characterized to determine the rotational relationship of the arene ring to the undercarriage, as has been suggested by theoretical studies. In fact, no such relationship can be seen, especially when combined with eight examples of structures with Z'> 1, where both staggered and eclipsed forms are found. (c) 2006 Elsevier B.V.
