20.500.12556/RUL-146426 Three angular Zn2Dy complexes showing the effect of remote coordination at Zn and counter ions on slow magnetic relaxation at Dy centres Three new angular trinuclear Zn2Dy complexes, [Dy{Zn(L)Cl}2(H2O)2]Cl3H2O (1), [Dy{Zn(L)Br}2(H2O)2](NO3) 6H2O (2) and [Dy{Zn(L)I}2(H2O)2](NO3)6H2O (3), derived from a methyl substituted o-vanillin based Schiff base ligand, N,N0 -bis(3-methoxy-5-methylsalicylidene)-1,2-phenylenediamine (H2L), have been synthesized and magneto-structurally characterised. In the complex cations in 1–3, the coordination environments of the Dy(III) ions are identical, but the apical coordination to the Zn(II) ion is different as it is bonded to different halide ions. Magnetic studies reveal that both 2 and 3 display field-supported slow magnetic relaxation, consistent with the isomorphic nature of the compounds, while 1 exhibits more pronounced singlemolecule magnetic behaviour. The direct fitting of the experimental data as well as the analysis with CASSCF calculations and SINGLE_ANISO module reveals a variation in magnetic anisotropy within the series and the presence of weak antiferromagnetic intermolecular interactions. Therefore, the present report highlights the influence of remote coordination at Zn and counter ions on magnetic anisotropy and on intermolecular antiferromagnetic dipolar interactions, leading to distinct magnetic dynamics in these systems. molekularni magnetizem Zn2Dy complexes molekularni magnetizem kompleks Zn2Dy true false true Angleški jezik Slovenski jezik Članek v reviji 2023-05-31 14:37:44 2023-05-31 14:37:47 2023-06-15 11:19:28 0000-00-00 00:00:00 2022 0 0 Str. 13546-13557 iss. 28, art. 13546 Vol. 46 2022 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 2022-01-01 544 1369-9261 10.1039/d2nj01759h 143373315 https://pubs.rsc.org/en/content/articlelanding/2022/NJ/D2NJ01759H 1 a483c0aa-ffaf-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=169620 Fakulteta za gradbeništvo in geodezijo Fakulteta za matematiko in fiziko 0 0 0
