Abstract
Complexes of the type Cs[Ln(SO4)2(H2O)3]H2O, (Ln=La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) were prepared from aqueous solution. The compounds are all isomorphous and crystallise monoclinic, space group P21/c,Z=4. Unit cell parameters were determined by the single crystal technique and correlated to the ionic radii of Ln3+.
IR spectra were recorded in the range 4000-250 cm−1 and tentatively assigned. The number of observed bands exceeds the predicted number by site symmetry selection rules, indicating coupling in the layer structure.
