Restricting magnetic interaction pathways in polyoxometalate salts of cationic nitronyl nitroxide free radicals.
Salts 1 and 2 that combine the [W6O19]2- Lindqvist anion with the cationic nitronyl nitroxide (NN) free radicals p-MepyNN+ and (n)Bu3NCH2NN+, respectively, have been synthesized and their structural and magnetic properties have been studied.

متن کاملThree new mononuclear tri-spin lanthanide-nitronyl nitroxide radical compounds: syntheses, structures and magnetic properties.
Based on the nitronyl nitroxide radical, 2-(4-(methoxycarbonyl)phenyl)-4,4,5,5-tetramethylimidazolin-1-oxyl-3-oxide (1, NITPhCOOMe), and three mononuclear tri-spin compounds [Ln(hfac)3(NITPhCOOMe)2] (Ln = Gd (2), Tb (3), Dy (4); hfac = hexafluoroacetylacetonate) are successfully synthesized and fully characterized. Compounds 2 and 4 are isostructural and crystallize in the C2/c space group, whi...
متن کاملSynthesis and Characterization of BINOL Based Axially Chiral Nitronyl Nitroxide Radicals.
Four novel axially chiral nitronyl nitroxides derived from S- or R-1,l'-bi-2-naphthol were synthesized and their crystal structures discussed. Circular dichroism spectra of these compounds showed significant Cotton effects between 200 and 400 nm, and also confirmed the optical activity of these enantiomers. The magnetic properties of the two pairs of nitronyl nitroxide radicals were characteriz...
متن کاملThe heart-protective mechanism of nitronyl nitroxide radicals on murine viral myocarditis induced by CVB3.
Our previous researches showed that nitronyl nitroxyl derivatives, NNP and NNVP were good anti-oxidants and provided radioprotective effects in C6 cells. The objective of the present study is to investigate the possible antiviral effects and underlying pharmacological of the two nitronyl nitroxide radicals against CVB3 in vitro and in vivo. The results showed that NNP and NNVP were some of the ...
