Two new glaserite-type orthovanadates: Rb(2)KDy(VO(4))(2) and Cs(1.52)K(1.48)Gd(VO(4))(2)

The crystal structures of dirubidium potassium dysprosium bis­(vanadate), Rb(2)KDy(VO(4))(2), and caesium potassium gadolinium bis­(vanadate), Cs(1.52)K(1.48)Gd(VO(4))(2), were solved from single-crystal X-ray diffraction data. Both compounds, synthesized by the reactive flux method, crystallize in...

description The crystal structures of dirubidium potassium dysprosium bis­(vanadate), Rb(2)KDy(VO(4))(2), and caesium potassium gadolinium bis­(vanadate), Cs(1.52)K(1.48)Gd(VO(4))(2), were solved from single-crystal X-ray diffraction data. Both compounds, synthesized by the reactive flux method, crystallize in the space group P [Image: see text] m1 with the glaserite structure type. VO(4) tetra­hedra are linked to DyO(6) or GdO(6) octa­hedra by common vertices to form sheets stacking along the c axis. The large twelve-coordinate Cs(+) or Rb(+) cations are sandwiched between these layers in tunnels along the a and b axes, while the K(+) cations, surrounded by ten oxygen atoms, are localized in cavities.
