Models for the interaction of nitrogen with transition metals. Part II. Crystal and molecular structure of carbonylchloro(4-fluorophenyl-di-imide-2C,N′)bis(triphenylphosphine)iridium(III) tetrafluoroborate acetone solvate

Abstract

The title complex forms yellow orthorhombic crystals space group P2₁2₁2₁, with Z= 4 in a unit cell of dimensions: a= 16·008(7), b= 18·620(10), c= 14·935(7)Å. The intensities of 1061 independent reflections were measured by counter methods. The structure was solved by Patterson and Fourier methods and refined by least squares to R 3·2% for 882 observed reflections. The complex cation contains an ortho-metallated aryl di-imide moiety, with acetone of crystallisation weakly hydrogen bonded to the hydrogen atom on N(1), the co-ordinated nitrogen atom, of the azo-function.
