摘要:

Two new layered lanthanide sulfates,[C10H10N2][Pr2(SO4)4(H2O)2](1)and[H5O2][Sm(SO4)2(H2O)3](2)were synthesized via solvothermal reaction and structurally characterized by single-crystal X-ray diffraction(XRD), infrared(IR) spectroscopy, thermal analysis, fluorescent spectra and inductively coupled plasma(ICP). Crystal data for compound 1, triclinic, P space group, a=0.8052(4) nm, b=0.9438(4) nm, c=1.4990(7) nm, α=79.450(5)°, β= 83.703(5)°, γ=74.048(5)°, V=1.0746(9) nm3, Z=2; for compound 2, monoclinic, P21/c space group, a=0.6599(11) nm, b=1.8940(3) nm, c=0.8765(14) nm, β=96.596(2)°, V=1.0883(3) nm3, Z=4. Structure analysis indicates that both the compounds exhibit a 2D corrugated layer structure, with protonated 4,4'-bipyridine cations and water dimmers (H5O2)+ located between the inorganic layers of compounds 1 and 2, respectively. Luminescent properties of compounds 1 and 2 were further investigated.
