Crystal and molecular structure of trichlorotris(tetrahydrofuran)scandium(III)
Abstract
The crystal structure of the title compound has been determined by direct methods from X-ray diffractometer data. Crystals are monoclinic plates, space group P21/c, with Z= 4 in a cell with a= 8·890(4), b= 12·842(6), c= 15·485(6)Å, β= 92·24(5)°. The structure was refined by least-squares techniques to R 0·077 for 1227 unique observed reflections. The substance exists as discrete molecules in which the scandium(III) ion environment is mer-octahedral. Mean Sc–O is 2·18, and mean Sc–Cl 2·41 Å.
