摘要：A series of lanthanide coordination polymers [Ln(NIPH)(HNIPH)(phen)] [Ln = Tb (1), Ho (2), Er (3), La (4), Sm (5)], [Ln(2)(NIPH)(3)(phen)(2)(H2O)]center dot(H2O) (Ln = Pr (6), Yb (7), [Ln(2)(NIPH)(3)(phen)2] [Ln = Eu (8), Nd (9)] (H2NIPH = 5-nitroisophthatic acid, phen = 1,10-phenanthroline) were hydrothermally synthesized and characterized by single-crystal X-ray diffraction. The frameworks constructed from dinuclear lanthanide building blocks exhibit three typical structure features: 1-3 possess one-dimensional double-stranded looplike chain structures, 4-7 have two-dimensional layer structure characteristics, 8 and 9 are the three-dimensional frameworks with pen topology. In 1-9, NIPH ligands adopt multidentate coordination modes. The supramolecular architectures of 1-9 show that the presence of phen ligands and nitro groups on NIPH induced the formation of numerous hydrogen bonds. The luminescent and magnetic properties of 8 and 9 are investigated.
