In presence of both [Dy(hfac)3] 2H2O and the Fe(II) salt, the heterobimetallic tetranuclear [FeDy3(hfac)8(H2O)2(opch)2] (2) was isolated, while the addition of the co-ligand 1,2-Bis(2-hydroxy-3-methoxybenzylidene) hydrazine (H2bmh) led to the formation of two heterobimetallic tetranuclear complexes with the formula [Fe3Dy(hfac)6(opch)2(H2bmh)] C6H14 (3) C6H14 and [Fe2Dy2(hfac)7(opch)2(H2bmh)] 0.5C7H16 (4) 0.5C7H16. Single crystal X-ray diffraction and dc magnetic investigation demonstrated that 3 and 4 involved the iron center in the +II and +III oxidation states. Dynamic magnetic measurements highlighted the single-molecule magnet behavior of 1 and 2 in a zero applied dc field primarily due to the ferromagnetic interactions taking place in these compounds.<\/jats:p>","DOI":"10.3390\/molecules28176359","type":"journal-article","created":{"date-parts":[[2023,8,30]],"date-time":"2023-08-30T10:30:52Z","timestamp":1693391452000},"page":"6359","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Single-Molecule Magnet Properties in 3d4f Heterobimetallic Iron and Dysprosium Complexes Involving Hydrazone Ligand"],"prefix":"10.3390","volume":"28","author":[{"given":"Bertrand","family":"Lefeuvre","sequence":"first","affiliation":[{"name":"CNRS, ISCR (Institut des Sciences Chimiques de Rennes)\u2014UMR 6226, University of Rennes, 35000 Rennes, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thierry","family":"Guizouarn","sequence":"additional","affiliation":[{"name":"CNRS, ISCR (Institut des Sciences Chimiques de Rennes)\u2014UMR 6226, University of Rennes, 35000 Rennes, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vincent","family":"Dorcet","sequence":"additional","affiliation":[{"name":"CNRS, ISCR (Institut des Sciences Chimiques de Rennes)\u2014UMR 6226, University of Rennes, 35000 Rennes, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marie","family":"Cordier","sequence":"additional","affiliation":[{"name":"CNRS, ISCR (Institut des Sciences Chimiques de Rennes)\u2014UMR 6226, University of Rennes, 35000 Rennes, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7601-1927","authenticated-orcid":false,"given":"Fabrice","family":"Pointillart","sequence":"additional","affiliation":[{"name":"CNRS, ISCR (Institut des Sciences Chimiques de Rennes)\u2014UMR 6226, University of Rennes, 35000 Rennes, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"141","DOI":"10.1038\/365141a0","article-title":"Magnetic bistability in a metal-ion cluster","volume":"365","author":"Sessoli","year":"1993","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"8694","DOI":"10.1021\/ja029629n","article-title":"Lanthanide Double-Decker Complexes Functioning as Magnets at the Single-Molecular Level","volume":"125","author":"Ishikawa","year":"2003","journal-title":"J.
