摘要：

Participation of the oxygen atoms of the siloxane framework of ligand 1, and not only the terminal hydroxyl groups, may be required for the coordinative saturation of a metal center. This surprising conclusion was drawn from the X‐ray structure analysis of the first rare earth metal complex with this type of ligand. Compound 1 serves as a molecular model for SiO2 supports for transition metal catalysts. (Figure Presented.) Copyright © 1994 by VCH Verlagsgesellschaft mbH, Germany
