Synthesis, 1H, 13C, and 29Si nuclear magnetic resonance spectra and crystal structure of trans-1,4-diphenyldecamethylcyclohexasilane

The coupling reaction between PhMeSiCl2 and Me2SiCl2 in the presence of Na/K alloy resulted in a variety of phenylated permethylcyclohexasilanes of which only trans-1,4-Ph2Me10Si6 could be obtained in pure form by repeated recrystallizations.It was studied by means of nmr (1H, 13C, and 29Si) and X-ray crystallography.The crystals are monoclinic, P21/c with a = 10.105(6), b = 14.77(1), c = 9.973(6) Angstroem, β = 94.08(5) deg, V = 1485(2) Angstroem3, and Z = 2 for 1922 unique "observed" reflections and the structure refined to an R index of 0.036.The molecule has site symmetry 1 and the chair conformation of cyclohexane, with the two phenyl rings occupying the equatorial positions.
