Sažetak
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.
