Thioester-functionalised and oxime-based hexametallic manganese(iii) single-molecule magnets

Abstract

Two novel hexametallic MnIII complexes of formulae [Mn63-O)2(H2N-sao)6(3-atpa)2(EtOH)6]·2EtOH·2H2O (1) and [Mn63-O)2(H2N-sao)6(6-atha)2(EtOH)6]·6EtOH (2) [H2N-saoH2 = salicylamidoxime, 3-hatpa = 3-(acetylthio)propionic acid, 6-hatha = 6-(acetylthio)hexanoic acid] have been synthesised by using thioester-carboxylate ligands and magnetostructurally characterised. 1 crystallises in the triclinic system with space group P[1 with combining macron] and 2 crystallises in the monoclinic system with space group P21/c. The study of the dc and ac magnetic susceptibility reveals single-molecule magnet behaviour for both compounds with spin-ground states S = 12 and S = 4 for 1 and 2, respectively. Hence, 1 and 2 are new members of the oxime-based family of [Mn6] single-molecule magnets, containing the thioester group functionalisation, which could be used to connect devices in molecular spintronics studies.
