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.
