Two novel 1D coordination polymers, [M(μ-2,3-pydc)(H2O)3]n (M = Cd for 1 and Co for 2) (2,3-pydcH2 = pyridine-2,3-dicarboxylic acid) have been hydrothermally synthesized. Both complexes were characterized by elemental analysis
and by IR and UV–Vis spectroscopy. Their molecular and crystal structures were determined by X-ray crystal structure analysis
and their thermal stability by TGA-DTA methods. Compound 1 crystallizes in the orthorhombic Pca2 space group, while compound 2 crystallizes in the triclinic P−1 space group. Polymeric chains of 1 and 2 are composed of M(II) ions bridged by pyridine-2,3-dicarboxylate ions (2,3-pydc) in N,O,O′ fashion. Distorted octahedral coordination geometry around the metal ions is completed by three water molecules. A wide
range of hydrogen bonding (of the O–H···O type) is also present in the crystal structures. These interactions lead to formation
of a 3D structure for 1 and 2D network for 2. 相似文献
