Gotcha! Unstable dithio- and diselenobenzoquinones can be trapped by coordination to an [(η5-C5Me5)Ir] moiety (see structure; gray C, white H, pink Ir, yellow Se). In vitro investigations on the anticancer activity of the resulting complexes showed them to be comparable to cis-platin. These organometallic species could form the basis for new anticancer agents.
