Abstract
Metal bis(dicarbollides) of the type M(B9-C2H11)2- (M = Co, Fe) have been incorporated into cationic organothorium complexes [Cp′2ThR]+X- (Cp′ = η5-(CH3)5C5; R = alkyl, H) as potential weakly coordinating unions. The reaction of Cp′2Th(CH3)2 with [HNEt3]+-[Co(B9C2H 11)2]- and [HNEt3]+[Fe(B9C2H11) 2]- in hydrocarbon solvents affords [Cp′2ThCH3]+[Co(B9C 2H11)2]- (1) and [Cp′2ThCH3]22+[Fe(B 9C2H11)2]2- (2), respectively. The structure of 2 reveals tight ion-pairing with three close Th⋯H-B bridging interactions (2.42(3), 2.50(3), 2.67-(4) Å). This level of Th coordinative saturation explains the unexpected chemical inertness of 1 and 2. The reaction of Cp′2Th[CH2Si(CH3)3] 2 with [HNEt3]+-[Co(B9C2H 11)2]- affords [Cp′2ThCH2Si(CH3)3] +-[Co(B9C2H11)2] - (3), which slowly undergoes hydrogenolysis to yield [C′2ThH]+[Co(B9C2H 11)2]- (4).
