Me. Villafuertecastrejon et al., CRYSTAL-STRUCTURE OF CS2KTBCL6 AND CS2KEUCL6 BY POWDER X-RAY-DIFFRACTION, Journal of solid state chemistry, 132(1), 1997, pp. 1-5
Cs2KTbCl6 and Cs2KEuCl6 from the elpasolite family (A(2)BLnX(6)) were
obtained by slowly evaporating to dryness a hot aqueous HCl solution o
f the appropriate chlorides and characterized by powder X-ray diffract
ion. Using WYR3 program software it was found that the title compounds
are cubic and isostructural to Rb2NaTmCl6. Cell parameters for Cs2KTb
Cl6 and Cs2KEuCl6 are a = 11.1224(3) Angstrom and a = 11.1633(3) Angst
rom, respectively. The space group for both compounds is Fm3m. (C) 199
