Abstract
The crystal structure of the title compound (III) has been determined by three-dimensional X-ray diffraction methods from diffractometer data. The crystals are orthorhombic, a= 22·535, b= 12·332, c= 13·917 Å, Z= 4, space group, P212121. The structure was solved by heavy-atom and three-dimensional Fourier methods, and refined by least-squares calculations to a final R of 0·098 for 2318 independent observed reflexions. The absolute configuration was determined by tne anomalous dispersion method.Keywords
