Microwave-assisted synthesis of a hexanuclear Mn(III) single-molecule magnet.

چکیده
The use of microwave heating has improved the reaction rate, enhanced the yield of an inorganic cluster complex, and allowed for the high-temperature/high-pressure synthesis of a Mn(III) single-molecule magnet.

The use of derivatised salicylaldoximes in manganese chemistry has led to the synthesis of a family of approximately fifty hexanuclear ([Mn(III)(6)]) and thirty trinuclear ([Mn(III)(3)]) Single-Molecule Magnets (SMMs). Deliberate, targeted structural distortion of the metallic core afforded family members with increasingly puckered configurations, leading to a switch in the pairwise magnetic ex...
متن کاملA new family of oxime-based hexanuclear manganese(III) single molecule magnets with high anisotropy energy barriers.
A magneto-structural study of two salicylamidoxime-based {Mn(6)} single-molecule magnets revealed that their anisotropy energy barriers, which can reach the current record for d-transition metal complexes, are strongly dependent upon the precise arrangement of ligands and the solvation state.
متن کاملSynthesis, crystal structure and magnetism of new salicylamidoxime-based hexanuclear manganese(III) single-molecule magnets.
Salicylamidoxime was used to synthesize 13 new polynuclear Mn(III) complexes. We present the crystallographic structures, the magnetic susceptibility and the magnetization measurements of eight of them (1-8) with the general formula [Mn(6)O(2)(H(2)N-sao)(6)(L)(2)(solvent)(4-6)] (L = carboxylate, chloride, 2-cyanophenolate; solvent = H(2)O, MeOH, EtOH, py). These complexes consist of two trinucl...
متن کاملA new versatile class of hetero-tetra-metallic assemblies: highlighting single-molecule magnet behaviour.
Hetero-tetra-metallic species based on hexanuclear assemblies [((valen)M1)Ln(OH2)2(μM2(CN)8)]2(2-) (Ln = Gd(III), Tb(III); M1 = Cu(II), Ni(II) and M2 = Mo(IV), W(IV)) and co-crystallized mononuclear complexes [M3(tpy)2](2+) (M3 = Ni(II), Ru(II), Os(II)) were identified, fully characterized, and shown to constitute a new class of single-molecule magnets.
متن کاملEffect of the Mn Oxidation State on Single-Molecule-Magnet Properties: Mn(III) vs Mn(IV) in Biologically Inspired DyMn3O4 Cubanes.
Inspired by the ferromagnetic coupling in the cubane model CaMn(IV)3O4 of the oxygen-evolving complex of photosystem II, 3d-4f mixed-metal DyMn3O4 clusters were prepared for investigation of the magnetic properties. For comparison, YMn(IV)3O4 and YMn(IV)2Mn(III)O4 clusters were investigated as well and showed ferromagnetic interactions, like the calcium analogue. DyMn(IV)3O4 displays single-mol...
