24_07/1985The cover page shows the—simplified—crystal structure of a new carbene complex which consists of an oxazirconaindanylidene fragment and a W(CO)5 fragment. The picture shows (upper row, left to right) the (OC)-W-(C3O)Zr units; the bonds from zirconium to the two cyclopentadienyl ligands are shown as “spikes”. In the solid state, the polymeric, helical structure is stabilized by solvent molecules (here toluene). Not only the structure, but also the one-step synthesis of the complex via a dehydrobenzene derivative of zirconocene is unusual. Further details are reported by G. Erker et al. on page 584.
