Abstract
The complexes of trinuclear TiCl3-O-TiCl3/TiCl2(O-(R)-mandelic acid methylester)2 I, C18H18Cl8O7Ti3, and dimeric TiCl3O-rac-mandelic acid methylester II, C18H18Cl6O6Ti2, were determined unambiguously by X-ray diffraction. Both crystal structures contain one solvent molecule toluene per complex. In structure I there are five independent complexes in the asymmetric unit cell. The formation of both the crystal structure as well as the coordination sphere of titanium is controlled sensitively by the chirality of mandelic acid methylesters.
