Crystal structure of 3,6-bis(pyridin-2-yl)-1,4-dihydro-1,2,4,5-tetrazine
(International Union of Crystallography, 2019)
Why 1,2‑quinone derivatives are more stable than their 2,3‑analogues?
(Springer Berlin Heidelberg, 2015-02-25)
In this work, we have studied the relative stability
of 1,2- and 2,3-quinones. While 1,2-quinones have
a closed-shell singlet ground state, the ground state for
the studied 2,3-isomers is open-shell singlet, except ...
Temperature-dependent polymorphism of N-(4-fluorophenyl)-1,5-dimethyl-1H-imidazole-4-carboxamide 3-oxide: experimental and theoretical studies on intermolecular interactions in the crystal state
(Springer US, 2014)
X-ray analysis of N-(4-fluorophenyl)-1,5-dimethyl-1H-imidazole-4-carboxamide 3-oxide reveals the temperature-dependent polymorphism associated with the crystallographic symmetry conversion. The observed crystal structure ...
Oxidation of 2-mercaptopyridine N-oxide upon iodine agent: structural and FT-IR studies on charge-assisted hydrogen bonds CAHB(+) and I…I halogen interactions in 2,2′-dithiobis(pyridine N-oxide) ionic cocrystal
(Springer Nature, 2019)
2-Mercaptopyridine N-oxide (I) undergoes spontaneous dimerization to the disulfide form due to reaction with iodine acting as an
oxidizing reagent. As a result, a di-N-oxide disulfide derivative of pyridine is obtained. ...
The substituent effect on benzene dications
(RSC Publishing, 2014-01-03)
It was recently postulated that the benzene ring and its 4n + 2 p-electron analogues are resistant to the
substituent effect due to the fact that such systems tend to retain their delocalized character. Therefore, the
4n ...
