Synthesis and molecular structure of Cd9(OC2H4OMe)18,2HOC2H4OMe, the first cadmium aggregate based on oxygen donor ligands
摘要:
The alcoholysis reactions between Cd[N(SiMe3)2]2 and functional alcohols such as 2-methoxyethanol produced soluble cadmium alkoxides. Cd9(OC2H4OMe)18, 2HOC2H4OMe has been characterized by X-ray diffraction. The compound corresponds to a centrosymmetric compact aggregate of nine cadmium atoms, the metals being hexa- or pseudo-hexa-coordinated. The alcohol molecules are hydrogen bonded to the terminal alkoxide groups. Cd-113 NMR established that the Cd9 cluster was retained in solution.
