Dodecanuclear [NiII8Ln₄] clusters and rings of corner-sharing {NiII2Ln₂} cubanes (Ln = Dy, Gd, Y); magnetic and magnetothermal properties 2025 Access copy available to the general public Unrestricted The solvothermal reaction of NiCl2·6H2O with 1,3,5-tri(2-hydroxyethyl)-1,3,5-triazacyclohexane, LH3, and Ln(OAc)3·4H2O in the presence of salicylaldehyde in MeOH leads to the formation of the dodecanuclear isostructural species [NiII8Ln4(L′)8(OAc)4(OH)8(H2O)4]·xH2O (Ln = Dy, x = 6 (1); Gd, x = 24 (2); Y, x = 10 (3); L′ = the dianion of the Schiff-base resulting from the reaction of salicylaldehyde and ethanolamine). The metallic core of the clusters describes a ring of corner-sharing {Ni2Ln2} cubanes assembled on a central, planar rectangular {Ln4} unit. Magnetization studies conducted on complexes 1–3 demonstrate the presence of dominant ferromagnetic exchange at low temperatures, which is largely attributed to the Ni⋯Ni interactions. The significant magnetocaloric effect observed in the Gd analogue has been assessed through heat capacity and magnetization measurements. info:eu-repo/grantAgreement/ES/AEI/CEX2023-001286-S info:eu-repo/grantAgreement/ES/DGA/E11-23R info:eu-repo/grantAgreement/ES/DGA/E12-23R info:eu-repo/grantAgreement/ES/MICINN/PID2021-124734OB-C21 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Agapaki, Eleftheria Charkiolakis, Emmanouil K.
