Here, two series of Ln\u2010radical complexes have successfully been built using an imino nitroxide biradical, namely, [Ln<jats:sub>2<\/jats:sub>(hfac)<jats:sub>6<\/jats:sub>(ImPhPyobis)<jats:sub>2<\/jats:sub>] (Ln<jats:sup>III<\/jats:sup>=Gd <jats:bold>1<\/jats:bold>, Tb <jats:bold>2<\/jats:bold>, Dy <jats:bold>3<\/jats:bold>) and [Ln<jats:sub>2<\/jats:sub>Cu<jats:sub>2<\/jats:sub>(hfac)<jats:sub>10<\/jats:sub>(ImPhPyobis)<jats:sub>2<\/jats:sub>] (Ln<jats:sup>III<\/jats:sup>=Gd <jats:bold>4<\/jats:bold>, Dy <jats:bold>5<\/jats:bold>; hfac=hexafluoroacetylacetonate and ImPhPyobis=5\u2010(4\u2010oxypyridinium\u20101\u2010yl)\u20101,3\u2010bis(1\u2019\u2010oxyl\u20104\u2019,4\u2019,5\u2019,5\u2019\u2010tetramethyl\u20104,5\u2010hydro\u20101<jats:italic>H<\/jats:italic>\u2010imidazol\u20102\u2010yl)benzene). For these biradical\u2010metal complexes, two imino nitroxide biradicals bind two Ln(III) ions via their oxygen atoms coming from 4\u2010oxypyridinium units to produce a binuclear {Ln<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub>} unit. Those imino nitroxide groups are free for complexes <jats:bold>1<\/jats:bold>\u2013<jats:bold>3<\/jats:bold>, however one of imino nitroxide groups of the biradical is ligated to the copper(II) ion for complexes <jats:bold>4<\/jats:bold> and <jats:bold>5<\/jats:bold>. The distinct magnetic relaxation behaviors are observed for two Dy derivatives, as revealed by ac magnetic studies: complex <jats:bold>3<\/jats:bold> presents one magnetic process with the effective energy barrier(<jats:italic>U<\/jats:italic><jats:sub>eff<\/jats:sub>) of 74.0\u2005K while complex <jats:bold>5<\/jats:bold> exhibits dual relaxation processes with <jats:italic>U<\/jats:italic><jats:sub>eff<\/jats:sub> values for the fast\u2010 and slow\u2010relaxation being 20.2\u2005K and 30.9\u2005K, respectively, which implies that the second coordination

relaxation.<\/jats:p>","DOI":"10.1002\/chem.202202239","type":"journal-article","created":{"date-parts":[[2022,8,18]],"date-time":"2022-08-18T05:54:20Z","timestamp":1660802060000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Influence
