Abstract
The crystal and molecular structure of the title compound have been determined from X-ray diffractometer data by direct methods. Crystals are monoclinic rods, space group P21/c, with Z= 6 in a cell with a= 13·54(1), b= 16·00(1), c= 13·40(1)Å, β= 93·97(5)°. The structure was refined by least-squares techniques to R 0·072 for 1680 observed reflections. The molecules exist as chlorine-bridged dimers, mean Sc–Cl 2·575 Å. The cyclopentadienyl groups are bonded in a penta-hapto-fashion, mean Sc–C 2·46 Å.Keywords
