It was shown that NNMn and INMn exhibit a sufficiently high kinetic stability both in solids and in solutions under normal conditions. Their structural characteristics, magnetic properties and electrochemical behavior are close to Re(I) analogs. This opens the prospect of using paramagnetic cymantrenes as prototypes in the design of Re(I) half-sandwiched derivatives for theranostics, where therapy is combined with diagnostics by magnetic resonance imaging due to the contrast properties of nitroxide radicals.<\/jats:p>","DOI":"10.3390\/molecules27217545","type":"journal-article","created":{"date-parts":[[2022,11,4]],"date-time":"2022-11-04T04:00:51Z","timestamp":1667534451000},"page":"7545","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["2-Imidazoline Nitroxide Derivatives of Cymantrene"],"prefix":"10.3390","volume":"27","author":[{"given":"Kseniya","family":"Maryunina","sequence":"first","affiliation":[{"name":"International Tomography Center SB RAS, Institutskaya Str. 3a, 630090 Novosibirsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5238-135X","authenticated-orcid":false,"given":"Gleb","family":"Letyagin","sequence":"additional","affiliation":[{"name":"International Tomography Center SB RAS, Institutskaya Str. 3a, 630090 Novosibirsk, Russia"},{"name":"Novosibirsk State University, Pirogova Str. 1, 630090 Novosibirsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8852-2759","authenticated-orcid":false,"given":"Galina","family":"Romanenko","sequence":"additional","affiliation":[{"name":"International Tomography Center SB RAS, Institutskaya Str. 3a, 630090 Novosibirsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6918-5459","authenticated-orcid":false,"given":"Artem","family":"Bogomyakov","sequence":"additional","affiliation":[{"name":"International Tomography Center SB RAS, Institutskaya Str. 3a, 630090 Novosibirsk, Russia"},{"name":"Novosibirsk State University, Pirogova Str. 1, 630090 Novosibirsk, Russia"},{"name":"N.
