The absolute structure of tetrakis(trimethylphosphine)copper(I) dichlorocopper(I)

G. Margraf, H.-W. Lerner, M. Wagner and M. Bolte

Abstract: The title compound, [Cu(C₃H₉P₄)₄][CuCl₂], previously reported by Chi et al. [J. Chem. Soc. Dalton Trans. (1992), pp. 3111-3117] has been rerefined with new intensity data. Geometric parameters agree quite well. However, our results are of significantly higher precision. Furthermore, our data indicate a different absolute structure than the one reported by Chi et al. The Cu, Cl atoms and one of the P atoms are located on a threefold rotation axis. As a result, there is just one third of both ions in the asymmetric unit.
