Abstract: Two lanthanide-organic frameworks[Dy2(MH)6]n·0.5DMF (1) and[Eu2(MH)6]n (2) (MH=maleichydrazide and DMF=N,N-dimethylformamide) have been synthesized and characterized by X-ray single-crystal diffraction and X-ray powder diffraction. Two complexes are both Triclinic P1 space group. Ln(Ⅲ)ions adopt same coordination environments, and seven-coordinated Ln(Ⅲ)atom form feature isostructural 3D structures, topological type:tsi. The luminescence properties of 1 and 2 were investigated. Under the excitation of 375 nm, the emission spectrum of complex 2 shows five peaks at 581, 593, 616, 652 and 705 nm, corresponding to 5D0→7FJ (J=0~4) transitions of Eu3+. The emission spectrum of complex 1 shows a peak at 618 nm, which plausibly arises from π*-π transition of ligands. |
