| Abstract | The first two examples of a novel series of organo-actinide complexes, [CpsUXL] (Cp = r/ 5 -CoH5, X = halide or pseudohalide anion, L = uncharged Lewis base), are described. The X-ray structure analysis of the system with X = NCS and L = CH3CN confirms an almost linear alignment (H3)CCNUNCS along with the coplanarity of the three Cp ring normals. The remarkable Lewis acidity of certain CpsUX-compounds appears to be essential for the formation of oligomeric species [Cp3UX]oo as well as for specific reactions of monomeric CP3UX. | ||
