| Abstract: | Three lanthanide-organic frameworks formulated as Yb2(1,3-pda)3(H2O)]n·nH2O (1) La2(2,5-pydc)3(H2O)2]n (2) and La(2,5-pydc)(2,5-Hpydc)(H2O)2]n·nH2O (3) (H21,3-pda=1,3-phenylenediacetic acid, H22,5-pydc=pyridine-2,5-dicarboxylic acid) have been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction. Both the frameworks of compounds 1 and 2 exhibit intricate 3D architectures which can be simplified as nets with mixed nodes. Compound 1 presents a very complicated net with five types of nodes comprising intersecting (3,4)-connected and CdSO4 nets. Compound 2 possesses a (4,4,6)-connected net with (4284)(4462)2(4966)2 circuit symbol. While compound 3 is a 2D layer based upon carboxyl-bridged LaIII chains. |
