Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 3543-72-4, Name is Ethyl 4-(1-methyl-5-nitro-1H-benzo[d]imidazol-2-yl)butanoate, SMILES is O=C(OCC)CCCC1=NC2=CC([N+]([O-])=O)=CC=C2N1C, belongs to imidazoles-derivatives compound. In a document, author is Liu, Guo-Cheng, introduce the new discover, SDS of cas: 3543-72-4.
Ligand-controlled Assembly of Cd(II) Metal-Organic Coordination Polymers Based on 3,5-Dinitrobenzoate and Flexible Bis(imidazole) Derivatives
Three new Cd(II) metal-organic coordination polymers, [Cd(bbi)(DNBA)(2)] (1), [Cd(bbbi)(DNBA)(2)] (2), and [Cd(dmbbbi)(DNBA)Cl]center dot 0.38H(2)O (3) [HDNBA = 3,5-dinitrobenzoic acid, bbi = 1-(1,4-butanediyl)bis(imidazole), bbbi = 1,1-(1,4-butanediyl)bis(benzimidazole), and dmbbbi = 1,1-(1,4-butanediyl)bis(5,6-dimethylbenzimidazole)], have been obtained from hydrothermal reactions of cadmium(II) chloride with the mixed ligands HDNBA and the three structurally related flexible bis(imidazole) derivatives. Single-crystal X-ray diffraction analyses have revealed that the dinuclear cadmium clusters acting as nodes interlinked by two mu(2)-carboxylic groups, are connected to four other clusters through bridging bbi (for 1) and bbbi (for 2) units to generate two extended two-dimensional (2-D) networks. Compound 3 features a 1-D zigzag chain structure. A systematic structural comparison of the title compounds indicates that the conformations and the steric hindrance of flexible bis(imidazole) derivatives each play an important role in the formation of the Cd(II) coordination polymers. The thermal stability of 1 and 2, and the luminescence behavior of 3 were also investigated.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 3543-72-4 is helpful to your research. SDS of cas: 3543-72-4.
