Application In Synthesis of 5,5′-Dimethyl-2,2′-bipyridine. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about A new polymorph of six-coordinated bis(5,5′-dimethyl-2,2′-bipyridine) nitratocopper(II) nitrate and its DNA interactions. Author is Goncalves, Guilherme R.; de Carvalho, Alexandre B.; Honorato, Joao; Oliveira, Katia M.; Correa, Rodrigo S..
Here, the authors present a new polymorph of the [Cu(5mebipy)(NO3)]NO3 complex (1, Form II), where 5mebipy means 5,5′-dimethyl-2,2′-bipyridine. 1 Was characterized by spectroscopic techniques and single-crystal x-ray diffraction. Form II presents a six-coordinated structure, meanwhile the Form I, previously reported, is five-coordinated with the nitrate ligand as monodentate. The mol. structures of both crystalline forms were compared based on intramol. aspects using Kleywegt’s anal. and the intermol. contacts evaluated by Hirshfeld surface studies. Also, the interaction of [Cu(5mebipy)(NO3)]+ with CT-DNA was carried out using viscosity and spectrophotometric titrations, exhibiting a binding constant of 2.57 × 104 M – 1. This study contributes to explore the intra and intermol. details of the new polymorph of [Cu(5mebipy)(NO3)]NO3 and its capability to interacts with CT-DNA.
As far as I know, this compound(1762-34-1)Application In Synthesis of 5,5′-Dimethyl-2,2′-bipyridine can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
