A series of 3-D lanthanide porous coordination polymers, [Ln(6)(BDC)(9)(DMF)(6)(H2O)(3)center dot 3DMF](n) [Ln = La, 1; Ce, 2; Nd, 3], [Ln(2)(BDC)(3)(DMF)(2)(H2O)(2)](n) [Ln = Y, 4; Dy, 5; Eu, 6], [Ln(2)(ADB)(3)(DMSO)(4)center dot 6DMSO center dot 8H(2)O] [Ln = Ce, 7; Sm, 8; Eu, 9; Gd, 10], {[Ce-3(ADB)(3)(HADB)(3)]center dot 30DMSO center dot 29H(2)O}(n) (11), and [Ce-2(ADB)(3)(H2O)(3)](n) (12) (H2BDC = benzene-1,4-dicarboxylic acid and H(2)ADB = 4,4'-azodibenzoic acid), have been synthesized and characterized. In 1-3, the adjacent Ln(III) ions are intraconnected to form 1-D metal-carboxylate oxygen chain-shaped building units, [Ln(4)(CO2)(12)](n), that constructed a 3-D framework with 4 x 7 angstrom rhombic channels. In 4-6, the dimeric Ln(III) ions are interlinked to yield scaffolds with 3-D interconnecting tunnels. Compounds 7-10 are all 3-D interpenetrating structures with the CaB6-type topology structure. Compound 11 is constructed by ADB spacers and trinulcear Ce nodes with a NaCl-type topology structure and a 1.9-nm open channel system. In 12, the adjacent Ce-III ions are intraconnected to form 1-D metal-carboxylate oxygen chain-shaped building units, [LN4(CO2)(12)](n), and give rise to a 3-D framework. Moreover, 6 exhibits characteristic red luminescence properties of Eu-III complexes. The magnetic susceptibilities, over a temperature range of 1.8-300 K, of 3,6, and 7 have also been investigated; the results show paramagnetic properties.
