摘要：
Two new complexes, namely {[La(pydc) (OAc) (H2O)]center dot 2H(2)O}(n) (1) and {[Tm2Cu(pydc)(4)(H2O)(6)]center dot 2H(2)O} (2) (H(2)pydc=2,5-pyridinedicarboxylic acid), have been synthesized and structurally characterized. Structure analyses reveal that complex 1 has intricate 3D micropore framework with 1D square channels, which is constructed by 2,5-pyridinedicarboxylate and acetate ligands. Complex 2 shows a 3D open framework in which 2,5-pydc(2-) dianion ligand adopts mu(2)-eta(1)-eta(1)- and mu(4)-bridge coordination mode. In addition, thermal stability for 1 and 2 and temperature-dependent magnetic susceptibilities for 2 have been investigated in detail. CCDC: 884201, 1; 884200, 2.
