2004 (English)In: Journal of Sol-Gel Science and Technology, Vol. 32, 25-29 p.Article in journal (Refereed) Published
The molecular alkoxide, ErNb2(OPri)13 was prepared by metathesis with 2KNb(OPri)6, KOPri and ErCl3, and structurally determined by single-crystal X-ray diffraction techniques. Each molecule contains a central Er3+-ion coordinates by six OPri groups placed, one via a double alkoxo-bridge and the other via a triple alkoxo.bridge. It is isostructural with LaNb2(OPri)13, in spite of the large difference in ionic radius between Er3+ and La3+ (16%). The compound was characterized by its IR- and UV-vis-NIR-spectroscopic fine structures, and found to be structurally intact in hexane:isopropanol solution.
