Reduction of CS2 to an ethanetetrathiolate by a hydride-bridged uranium–iridium heterobimetallic complex

We report the synthesis of a heterobimetallic U(iii)–Ir species which reacts with CS2 to form the novel ethanetetrathiolate fragment via hydride insertion and C–C coupling. Computational studies suggest the formation of a radical intermediate, which may couple with another equivalent to form the final product.
