Different synthesis routes have been studied for the preparation of a new oxoalkoxide, Er 2 Ti 4 O 2 (OEt) 18 (HOEt) 2 (Etβ«Ψβ¬ C 2 H 5 ). The compound was best prepared by reacting KOEt and Ti(OEt) 4 first with water and then with ErCl 3 . The structure was determined by single-crystal X-ray diffract

The optical properties of Ln 2 Ti 2 S 2 O 5 compounds (Ln=Nd, Sm, Gd, Tb, Dy, Ho, Er, and Y) have been measured. Diffuse reflectance spectra revealed a strong absorption band above 2 eV, which explains the color of the compounds. Moreover, other bands, with a lower intensity, have been attributed to
