Two novel 2D decapolyoxotungstates constructed up by coordinated lanthanides

Two layer compounds, [(H2O)Na(μ-DMSO)3Ln(DMSO)4(W10O32)]n (Ln = La, 1, Ln = Ce, 2), which were synthesized by the reaction of sodium tungstate and lanthanide chloride in the solution of DMSO and water, have been characterized by IR, Raman, elemental analysis, TGA and X-ray single crystal diffractometer. Single crystal structure analysis shows that the same two-dimensional layer structure for 1 and 2 represents the first example that the basic decapolyoxotungstates building blocks was linked up into multi-dimensional structure by DMSO coordinated lanthanides (La or Ce) and sodium ions.
