| Abstract: Three new lanthanide complexes with semi-rigid V-shape 4,4′-dicarboxybiphenyl sulfone, [Nd2(dbsf)3(DMF)2.25(H2O)1.75]·1.25DMF·0.5MeOH (1)，[Yb2(dbsf)3(H2O)2]·1.5H2O (2) and [Er2(dbsf)3(H2O)2]·0.75H2O (3)(H2dbsf=4,4′-dicarboxybiphenyl sulfone, DMF=N,N-dimethyl formamide, MeOH=methanol) were synthesized and characterized by X-ray diffraction single-crystal structural analysis. The crystal structures show that complex 1 is composed of 3D lanthanide-organic framework (LnOF) with 1D channels, in which uncoordinated DMF and MeOH molecules are filled; while the complexes 2 and 3 have 3D LnOFs with cavities, in which lattice water molecules are located. Their formation and structural characteristics are possibly due to the semi-rigid V-shape ligand H2dbsf and lanthanide contraction effect. CCDC: 683617, 1; 683618, 2; 683619, 3. |
