Zusammenfassung
The reactivity of Cp*Sb-4(4) (1) towards ionic compounds and transition metal complexes with labile ligands was investigated in order to synthesize polyantimony ligand complexes. The silver salts [Ag][X] and the metalate Na[Cp*Mo(CO)(3)] were primarily used, leading in the raction with Cp*Sb-4(4) to the formation of [Cp*Sb-2][X] (X = TEF (2a), FAL (2b)), [(Cp*Mo(CO)(3))(3)(mu(3)-Sb-3)] (3) and ...

The reactivity of Cp*Sb-4(4) (1) towards ionic compounds and transition metal complexes with labile ligands was investigated in order to synthesize polyantimony ligand complexes. The silver salts [Ag][X] and the metalate Na[Cp*Mo(CO)(3)] were primarily used, leading in the raction with Cp*Sb-4(4) to the formation of [Cp*Sb-2][X] (X = TEF (2a), FAL (2b)), [(Cp*Mo(CO)(3))(3)(mu(3)-Sb-3)] (3) and [Cp*Mo(CO)(2)(eta(3)-Sb-3)] (4), respectively. The reaction of 1 with the transition metal complexes [(Cp ''' M)(2)(tol)] leads to a degradation of the original Sb-4 unit and to the formation of [(Cp ''' M)(4)(mu(3)-Sb)(4)] (M = Ni (5); Co (6)). Towards [(CpFe)-Fe-R(CO)(2)](2), substitutions on the antimony atoms were observed to give [{(CpFe)-Fe-R(CO)(2)}(4)(mu(4)-Sb-4)] (Cp-R = Cp '' (7a), Cp ''' (7b)). All complexes were characterized by XRD and spectroscopic methods.
