Abstract

original image

The chain gang! Tetrametallic iridium chains with the metal atoms in an average oxidation state 1.5 and bound by unsupported metal–metal bonds have been effectively connected to organic fragments with delocalized π electrons, such as 1,4-diethynylbenzene (see figure). This connection allows an electronic communication along the whole chain spanning around 30 Å and sheds light on the possible use of this type of molecule as “molecular wires”.
