| Abstract: | Some cationic five coordinate complexes of formula [Os(CO)(NO)L2A]PF6 (L = tertiary phosphine, A = an acetylene) have been prepared by reaction of the appropriate acetylene with [Os(CO)(NO)L2(acetone)]PF6; the variable temperature 1H NMR spectra of some of these indicate that the coordinated π-acetylene undergoes fluxional behaviour. |
