Reduction of the bulky 8-annulene thorium complex [Th{l{underscore}brace}COT(TNS){sub 2}{r{underscore}brace}{sub 2}] (COT(TBS){sub 2} = {eta}-C{sub 8}H{sub 6}(tBuMe{sub 2}-Si){sub 2}-1,4) by potassium yields the anionic compound {l{underscore}brace}Th[COT(TBS){sub 2}]{sub 2}{r{underscore}brace}K {center{underscore}dot} (DME){sub 2}, which was crystallographically characterized and is the first sandwich complex of Th(III).l EPR spectroscopy indicates that the molecule possesses a 6d{sup 1} ground state. A structural comparison is made with the isostructural uranium(III) complex and the thorium(IV) parent compound.
