- Abstract
A versatile one-pot strategy was used to synthesize two large, purely inorganic selenotungstates, nanocluster K6Na16[Ce6Se6W67O230(OH)6(H2O)17]⋅47 H2O ( 1) and layer K9Na5Ce(H2O)4[Ce6Se10W51O187(OH)7(H2O)18]⋅45 H2O ( 2), by combining cerium centers and SeO32− heteroanion templates. Compound 1 displays a Ce-stabilized hexameric nanocluster with one rhombus-like {W4O15(OH)3} unit in the center, whereas compound 2 is the first example of a Ce-bridged layer selenotungstate network based on linkage of the unusual {Ce6Se10W51O187(OH)7(H2O)18} clusters and additional Ce(H2O)4 fragments via Ce-O-Se bridges. The compounds were characterized by elemental analyses, IR spectroscopy, thermogravimetric analyses, powder and single-crystal X-ray diffraction, and electrospray ionization mass spectrometry. Moreover, the electrochemical property of compound 1 was also investigated.
