摘要：

A terminal C-H bond in H2C = CHtBu can be cleaved with, for example, Na2CO3/EtOH as base in the coordination sphere of an Ir center, leading to [{CH2(C5H4)2}{Ir2(mu-CH = CHtBu)2}] (1), a complex with an extremely short Ir-Ir bond. Unusual are the +2 oxidation state of the two Ir atoms, the bridging through three organic ligands, and the absence of terminal ligands. A similar structure to that of 1, although without CH2 bridges between the Cp rings, is shown on the right.
