Samarium compounds lattice parameter

Sm-Cu-Sb. A ternary compound of samarium with copper and antimony of the stoichiometric ratio 3 3 4 was identified and studied by means of X-ray analysis by Skolozdra et al. (1993). The compound Sm3Cu3Sb4 was found to have the Y3Au3Sb4 type structure with a lattice parameter of a = 0.9620 (X-ray powder diffraction). For experimental details, see the Y-Cu-Sb system. 

The crystal structure of the compound SmPd2Ge (6) was found to be of the YPd2Si type (a = 0.7501, i = 0.6996, c = 0.5673 X-ray powder diffraction) by Jorda et al. (1983). For the experimental procedure, see LaPd2Ge under La—Pd-Ge. The starting materials were palladium 99.99 mass% germanium, specpure quality samarium 99.9 mass%. Barakatova (1994) confirmed the structure type and determined the lattice parameters a = 0.7504, b= 0.6995, c = 0.5680 from X-ray powder analysis. 

Berkelium(iii) orthophosphate has been prepared and characterized by x-ray powder diffraction and solid-state absorption and Raman spectroscopy [112, 113]. Analysis of the x-ray data has shown this compound to be isostructural with samarium and europium orthophosphates and to exhibit similar lattice parameters [112]. The structure type was confirmed by the direct correlation of the Raman spectrum of BkP04 with those of the isostructural lanthanide orthophosphates [113].
