Abstract:X-ray diffraction data were collected at 20°C on a computer-controlled Philips diffractometer (PW 1100). The structure was solved by direct methods and refined by the full-matrix least-squares method to an R of 0.065 (weighted R 0.046). The molecule in the crystal is of lower symmetry than C2,.. The geometry of the molecule has been compared with NMR results obtained by Danieli, Lunazzi & Veracini [J. Chem. Soc. Perkin II, (1976), pp. 19-201. As a result a C-H bond-length correction of 0.09 (2) A was found.
