摘要
Reaction of the tungsto-antimonate [Sb8W36O132](24-)polyoxometalate with late trivalent lanthanide cations (from Gd to Lu) gives rise to the formation of eight isostructural molecular compounds [{Sb-3(mu(3)-O)(2)Ln(H2O)Ln(H2O)(2)(SbW10O37)(SbW8O31)}(2)](22-)(Ln = Gd-III(1), Tb-III(2), Dy-III(3), Ho-III(4), Er-III(5), Tm-III(6), Yb-III(7), Lu-III(8)). All compounds were characterized by routine solid-state techniques (IR spectroscopy, TGA, single-crystal X-ray diffraction) and, by SAXS measurements in aqueous solutions to assess their stabilities. Luminescent properties of compounds5and7were also studied.
