摘要：

Coordination of a bidentate ligand to a (salen)Ti(IV) complex causes conversion of the pseudoplanar salen ligand, which binds the Ti with mer (octahedral) geometry, into a helical ligand, which has fac geometry about the metal. If either the salen or the bidentate ligand contains a resolved, stereogenic center, the resulting he cal complex is chiral. X-ray crystallographic data correlate the sense of helical; deformation with substitution configuration either of the salen or of the a-hydroxy carboxylato ligands. These X-ray data can be quantatitively correlated with circular dichroism (CD) spectra, which demonstrates that the simple spectroscopic technique can provide an acceptable means of determining the magnitude of the helical deformation of fac-salen adducts, according to chiral exciton theory.synlp; 136q.
