Kurzfassung englisch:
The continuously accelerating techno-logical progress generates a high demand for new materials with unique properties. In this emerging field, hybrid materials show properties not accessi-ble with conventional materials. A detailed under-standing of the chemistry of precursors for the preparation of hybrid materials on a molecular level is a prerequisite for a deliberate design of new materials.
In this work the synthesis and characterization of yttrium alkoxides modified with β-ketoesters is reported. Three types of oxo/hydroxo/alkoxo clus-ters were obtained, the two nonanuclear clusters Y9O(OH)9(OiPr)8(iprac)8 and Y9O(OH)9(iprac)16 and the tetranuclear cluster [Y2(OH)(iprac)5]2 (OiPr = isopropoxide; iprac = isopropyl acetoacetate). The compounds were characterized by crystallo-graphic and spectroscopic methods.
