Résumé

Abstract Thorocene [Th(Cot)2] (Cot = η8-C8H8) readily reacts with 2,2′-bipyridine to give [Th(Cot)2(κ2-bipy)], which has an unusual bent geometry. This compound is rapidly reduced by \KC8\ into the anionic derivative [(Th(Cot)2(κ2-bipy)]−. X-ray diffraction studies suggest the latter to be a Th(IV) compound with the bipyridyl radical anion. These complexes are rare examples of bent actinocene [An(Cot)2(L)]q− (q = 0, 1; An = actinide) and bipyridine-containing thorium species.
