Abstract

One dinuclear structure complex, Zn₂(L¹)₂Cl₄ (1), two coordination polymers (CPs), {[Cd(L¹)₂Cl₂]·2H₂O}n (2) and [Cd(L¹)₃(NO₃)₂]n (3), and one mononuclear structure complex, [Co(L²)₂(H₂O)₄]·6H₂O (4) [L¹ = N-(pyridine-4-methyl)-1H-benzo[d]imidazole-2-amine, HL² = 4-(1H-imidazo[4,5-c]pyridine-2-yl)benzoic acid] have been successfully synthesized and characterized. Complexes 1 and 4 exhibit zero-dimensional (0D) structures, complex 2 has a two-dimensional (2D) structure, and complex 3 displays a one-dimensional (1D) structure. Complexes 1–3 exhibit good adsorption properties toward the anionic dye Congo red (CR), with adsorption capacities of 1018, 222, and 990 mg·g⁻¹, respectively. Additionally, the results of magnetic property studies showed that complex 4 exhibits antiferromagnetic behavior.

期刊介绍： The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including: • Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.) • Chemical intermediates • Molecules in excited states • Biological molecules • Polymers. The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example: • Infrared spectroscopy (mid, far, near) • Raman spectroscopy and non-linear Raman methods (CARS, etc.) • Electronic absorption spectroscopy • Optical rotatory dispersion and circular dichroism • Fluorescence and phosphorescence techniques • Electron spectroscopies (PES, XPS), EXAFS, etc. • Microwave spectroscopy • Electron diffraction • NMR and ESR spectroscopies • Mössbauer spectroscopy • X-ray crystallography • Charge Density Analyses • Computational Studies (supplementing experimental methods) We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
