Abstract
The double selenates, RbLn(SeO4)2 (where Ln = La, Ce, Pr or Nd) are synthesized and studied crystallographically. These are monoclinic with space group P21/n containing four formulae per unit cell. The lattice parameters are: for RbLa(SeO4)2, a = 8.036(8), b = 5.382(5), c = 18.11(2) A, β = 92.00(12)°, V = 783 A3, Dobs = 4.34, Dcalc = 4.33 Mg m−3; for RbCe(SeO4)2, a = 8.012(10), b = 5.376(7), c = 18.04(3) A, β = 91.93(17)°, V = 777 A3, Dobs = 4.37, Dcalc = 4.37 Mg m−3; for RbPr(SeO4)2, a = 7.969(11), b = 5.352(7), c = 17.91(3) A, β = 91.67(13)°, V = 764 A3, Dobs = 4.43, Dcalc = 4.46 Mg m−3; for RbNd(SeO4)2, a = 7.943(14), b = 5.333(10), c = 17.91(4) A, β = 91.72(18)°, V = 758 A3, Dobs = 4.44, Dcalc = 4.52 Mg m−3. The JCPDS Powder Diffraction File No. for RbCe(SeO4)2 is 33–1496.
