Crystal data for two series of solid solutions: (Rb_xK_1−x)MgCr₂(VO₄)₃and (Tl_xK_1−x)MgCr₂(VO₄)₃

Abstract

Complete solid solution is observed amongst the compounds of the type M1MgCr2(VO4)3 (where M1 = K, Rb or Tl). The solid-solution series obtained show linear changes in peak positions and peak intensities in their X-ray diffraction patterns. The crystallographic behaviour with respect to the value of x for (RbxK1−xMgCr2(VO4)3 and (TlxK1−x)MgCr2(VO4)3 solid solutions is discussed.
