Abstract
Abstract Complexes of formula (η-C 5 H 5 2 Rh 2 {CF 3 C 2 CF 3 · RNCO} have been prepared by three methods, from reactions between organic isocyanates and (η-C 5 H 5 ) 2 Rh 2 (CO)(CF 3 C 2 CF 3 ) or (η-C 5 H 5 ) 2 Rh 2 (CO) 2 (CF 3 C 2 CF 3 ); by treatment of (η-C 5 H 5 ) 2 Rh 2 (CO)(CF 3 C 2 CF 3 ) with organic azides; and by oxidation with Me 3 NO of the organic isocyanide in (η-C 5 H 5 ) 2 Rh 2 (CO)(CNR)(CF 3 C 2 CF 3 ). The crystal and molecular structure of the complex (η-C 5 H 5 ) 2 Rh 2 {CF 3 C 2 CF 3 · RNCO} with R = Ph has been determined from single crystal X-ray diffraction data. This reveals that the isocyanate has condensed with the hexafluorobut-2-yne to form an amide ligand of the form C(CF 3 )C(CF 3 )C(=O)N(R); this bridges the two rhodium atoms in a μ 2 η 3 -manner.
