Studies on metal-acetylene complexes X. Spectroscopic studies of hexafluorobut-2-yne complexes, and the X-ray structure of an acetylene compound containing a chiral, chelating diphosphine

The acetylene complex ()-(N,N-bis(diphenylphosphino)-1-phenethylamine) (hexafluorobut-2-yne)platinum(O) has been prepared, and its structure determined by X-ray analysis. Crystals are monoclinic, space group P21, with a cell of dimensions a = 11.177(2), b = 15.690(3), c = 19.655(4) Å and β = 94.46(1)°. Intensity data collected on an automated four-circle diffractometer was used for full-matrix least-squares refinement on F, which converged at …
