Abstract

Two compounds of the elpasolite family (A2BLnX6), Cs2KTbCl6 and Cs2KEuCl6, were obtained {by evaporating to dryness a hot aqueous HCl solution of the appropriate chlorides [Morss etal., Inorg. Chem. 9, 1771 (1970)]} and characterized by powder X-ray diffraction. Title compounds are isostructural with cubic Rb2NaTmCl6 and correspond to the perovskite related structure with space group Fm3m, cell parameters 11.1294(6) and 11.1618(4) Å, V=1378.5(2), and V=1390.5(1) Å3, respectively.
