Paper Title:
Structural Refinement and Homogeneity Range of Sm6Al3Si
  Abstract

The structure of the compound Sm6Al3Si was refined from X-ray powder diffraction data (Tb6Al3Si structure type, space group I4/mcm, a = 11.733(1), c = 15.266(2) Å, Z = 8, RB = 0.0569). Its homogeneity range extends from 10 to 22 at.% Si and the following formula Sm6Al3-1.8Si1.0-2.2 is proposed for the compound studied. The Al and Si atoms are surrounded by Sm atoms forming trigonal prisms, square prisms and antiprisms.
