So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Goncalves, Guilherme R.; de Carvalho, Alexandre B.; Honorato, Joao; Oliveira, Katia M.; Correa, Rodrigo S. researched the compound: 5,5′-Dimethyl-2,2′-bipyridine( cas:1762-34-1 ).Name: 5,5′-Dimethyl-2,2′-bipyridine.They published the article 《A new polymorph of six-coordinated bis(5,5′-dimethyl-2,2′-bipyridine) nitratocopper(II) nitrate and its DNA interactions》 about this compound( cas:1762-34-1 ) in Journal of Molecular Structure. Keywords: copper methylbipyridine preparation crystal structure DNA binding Hirshfeld surface. We’ll tell you more about this compound (cas:1762-34-1).
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.
