Аннотация

A new 3-D europium sulfate Eu2(H2O)4(SO4)3 1 is synthesized solvothermally and characterized by single crystal X-ray diffraction, IR spectrum, TG, powder XRD, and ultraviolet excitation and emission spectrum. This compound crystallizes in the triclinic system with the space group P-1, a = 6.7520(9) Å, b = 9.1077(12) Å, c = 10.5910(14) Å, α = 94.432(2)°, β =
= 107.1170(10)°, γ = 99.160(2)°, V = 609.17(14) Å3, Z = 2. The open framework of the title compound is an eight-membered ring channel along the crystallographic a-axis, which is built up by EuO8 polyhedra and SO4 tetrahedra.
