Crystal structures of the RCuPbSe3 (R = Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu) compounds

The crystal structures of the RCuPbSe3 (R = Gd, Th, Dy, Ho, Er, Tm, Yb and Lu) compounds (beta-BaLaCuSe3 structure type, space group Pnma, Pearson symbol oP24) were determined by means of X-ray powder diffraction: a = 1.0687(2) nm, b = 0.40858(5) nm, c = 1.3443(2) ran, R1 = 0.0856 (GdCuPbSe3); a = 1...
