资源简介：
Two series of lanthanide metal–organic frameworks,
[Ln(FDA)(OX)0.5(H2O)2]·(H2O) (1Ln) (Ln = Pr 1, Nd 2, Eu 3, Gd 4, Tb 5), [Ln(FDA)(OX)0.5(H2O)2]·(H2O) (2Ln) (Ln = Sm 6, Tb 7, Dy 8, Ho 9, Yb 10) (OX = oxalate),
have been prepared by reacting Ln(NO3)3·6H2O with furan-2,5-dicarboxylic acid (H2FDA) at different
temperatures under hydrothermal conditions. All the complexes are
characterized by elemental analysis, IR, X-ray powder diffraction,
and single-crystal X-ray diffraction. Structure analyses show that 1Ln and 2Ln are supramolecular isomerisms. 1Ln possesses a three-dimensional network with monoclinic
space group P21/c, whereas 2Ln exhibits a three-dimensional framework with monoclinic
space group C2/c. The distinct architectures
of these two series of ten complexes indicated that the reaction temperature
plays an important role in the formation of such coordination structures.
Meanwhile, the photoluminescent properties of 4, 5, 7, and 8 are also investigated
in the solid state at room temperature.
