摘要

Seven isomorphous alkali metal lanthanide selenites, Na(4)Ln(4)(SeO3)(7)O. nH(2)O (Ln = Gd, Tb, Dy, Ho, Er, Tm, and Yb), exhibiting a riew structure type, have been prepared by hydrothermal methods. The four crystallographically unique Ln(3+) cations Within the structure exhibit three different coordination environments that are best described as bicapped trigonal prisms, trigonal dodecahedra, and pentagonal bipyramids. These polyhedra edge- and corner-share to-yield diamond-shaped channels: that extend along the a axis and are approximately 8.4 angstrom X 10.5 angstrom. These channels house alkali metal cations and disordered water molecules. The Ho-analog was chosen for ion-exchange studies that indicate that the Na+ cations in the channels can be selectively exchanged for Rb+, but ion exchange with other monovalent cations does not occur.
