Abstract
Reaction of 2,6-diallylpyridine (DAP) with Rh(I) compds. gave complexes of the type [RhCl(DAP)]n, RhCl(L)(DAP) (L = CO, PPh3), [Rh(diene)(DAP)]Y [diene = 1,5-cyclooctadiene (COD), norbornadiene (NBD); Y = [RhCl2(diene)], CuCl2, ClO4]. The crystal structures of [Rh(COD)(DAP)][RhCl2(COD)] and [Rh(COD)(DAP)][CuCl2] were detd. by x-ray crystallog. The crystals consisted of cationic [Rh(COD)(DAP)]+ and anionic [Rh(COD)Cl2]- and [CuCl2]- complexes, resp. The cations were similar in the two compds., and the coordination around the Rh atoms was trigonal bipyramidal, with a short Rh-N axial bond and 4 η2-C:C olefinic interactions.File in questo prodotto:
