Three new metal-organic complexes, [Cd4(2,3-Pdc)4 · 4H2O] (I), [Fe4(2,3-Pdc)4 · 12H2O] (II), [Ba8(2,3-Pdc)4 · 12H2O] (III) (2,3-Pdc = 2,3-pyridinedicarboxylic acid), have been synthesized and characteristic by IR spectrum, elemental analysis, single-crystal X-ray diffraction, thermogravimetric analysis. X-ray structure analysis shows that complex I is 3D structure, complex II and complex III are 1D chain structures (CIF files CCDC nos. 1002757 (I), 1002888 (II) and 1002980 (III)). 2,3-Pdc has many kinds of coordination mode, so it can form many different of coordination polymers. Complexes can be packed by the weak C-H⋯O, N-H⋯O and π-π interactions.
