Three polyoxotungstates of Sn super(II), Pd super(II), and Rh super(II), Na sub(8)[H sub(2)SnW sub(1 2)O sub(42)].nH sub(2)O [1, n = 22.75 (1a) and n = 31.10 (1b)], Na sub(2)K(H)[Pd(H sub(2)O) sub(4)][H sub(2)W sub(12)O sub(48){Pd(H sub(2)O) sub(3) } sub(2)].10H sub(2)O (2), and Na sub(8)[Rh sub(2)(H sub(2 )O) sub(2)(W sub(5)O sub(18)) sub(2)].21.25H sub(2)O (3) were obtained. The complexes were characterized by X-ray analysis, solid-state super(1)H NMR spectroscopy, IR spectroscopy, thermogravimetric analysis, and elemental analysis. Polyoxotungstates of Sn super(II), Pd super(II), and Rh super(II), Na sub(8)[H sub(2)SnW sub(1 2)O sub(42)].nH sub(2)O, Na sub(2)K(H)[Pd(H sub(2)O) sub(4)][H sub(2)W sub(12)O sub(48){Pd(H sub(2)O) sub(3) } sub(2)].10H sub(2)O, and Na sub(8)[Rh sub(2)(H sub(2 )O) sub(2)(W sub(5)O sub(18)) sub(2)].nH sub(2)O, were obtained and characterized by X-ray analysis and solid-state super(1)H NMR spectroscopy.
