Hydrothermal synthesis and structure of three novel open-framework lanthanide sulfate–oxalates
摘要:
Three novel hybrid open-framework lanthanide sulfate-oxalates, {[NH4][Ln(H2O)(SO4)(C2O4)]}(n) [Ln = Y (1), La (II), Sm (III)] have been synthesized via hydrothermal reaction, and characterized by single crystal X-ray diffraction, powder X-ray diffraction, infrared spectrophotometry, thermal gravimetric analysis and fluorescence analysis. These three compounds were isostructural, and all crystallized into the monoclinic system with space group of P2(1)/n. In their structures, LnO(8) dodecahedra, SO4 tetrahedral and C2O4 groups are linked to give rise to a three-dimensional open-framework, which contains two kinds of 12-membered ring channel systems running along the a and b axis, respectively.
