    Description / Table of Contents: On a Novel Reduction Procedure for the Preparation of Pure SmF2, JCuF2, YbF2, SmS, YbS, and EuOA technique is described, by which the compounds SmF2, EuF2, YbF2, SmS, YbS and EuO can be prepared by reduction of the trifluorides, sesquisulfides, and of europium sesquioxide, respectively, with the gaseous rare earth metals. By this technique the contamination of the reaction products with several specific impurities, usually contain-ed in the condensed rare earth metals; can be avoided. Analytical data and lattice para-meters of the compounds prepared by this method are communicated.
    Notes: Es wird eine Methode beschrieben, mit, der sich die Verbindungen SmF2, EuF2, YbF2, SmS, YbS und EuO durch Reduktion der Trifluoride, Sesquisulfide bzw. von Europiumsesquioxid mit den entsprechenden gasförmigen Seltenerdmetallen frei von bestimmten die kondensierten Metalle gewöhnlich begleitenden Verunreinigungen darstellen lassen. Analysendaten und Gitterparameter der auf diese Weise dargestellten Verbindungen werden mitgeteilt.
