Achiral single molecule magnet and chiral single chain magnet.
An achiral molecular square and a chiral chain composed of cyanide bridged Fe(III) and Ni(II) ions were prepared, and they act as a single molecule magnet and a chiral single chain magnet, respectively.
متن کاملA single molecule magnet to single molecule magnet transformation via a solvothermal process: Fe4Dy2 → Fe6Dy3.
Two series of heterometallic Fe(III)-Ln(III) compounds, [FeLn(μ3-OH)2(mdea)4(m-NO2C6H4COO)8]·3MeCN where Ln = Y (1) and Dy (2) and [FeLn(μ4-O)3(μ3-O)(mdea)5(m-NO2C6H4COO)9]·3MeCN where Ln = Y (3) and Dy (4), were synthesized. Compounds 1 and 2 were obtained under ambient conditions, whereas 3 and 4 were obtained via a solvothermal transformation process by heating 1 or 2 at 120 °C in MeCN. The ...
متن کاملA hydride-ligated dysprosium single-molecule magnet.
An experimental and ab initio computational study of an unsymmetrical, hydride-bridged di-dysprosium single-molecule magnet is reported.
متن کاملStudies of a linear single-molecule magnet.
Reaction of the dinuclear complex [Mn2O2(bpy)4](ClO4)3 with H3cht (cis,cis-l,3,5-cyclohexanetriol) in MeCN produces the complex [Mn3(Hcht)2(bpy)4](ClO4)3.Et2O.2MeCN (1.Et2O.2MeCN). Dc magnetic susceptibility measurements reveal the existence of weak ferromagnetic exchange between the three Mn ions, leading to a spin ground state of S = 7, with D = -0.23 cm(-1). W-Band (94 GHz) EPR measurements ...
متن کاملSynthesis and characterization of a Mn22 single-molecule magnet and a [Mn22]n single-chain magnet.
The reactions of [Mn12O12(O2CEt)16(H2O)4] with phenylphosphinic acid (PhHPO2H) in MeCN and MeCN/CH2Cl2 have led to isolation of [Mn22O12(O2CEt)22(O3PPh)8(H2O)8] (2) and [Mn22O12(O2CEt)20(O3PPh)8(O2PPhH)2(H2O)8]n (3), respectively, both containing PhPO3(2-) groups from in situ oxidation of PhHPO(2)(-). Complex 2 is molecular and consists of two Mn9 subunits linked by four additional Mn atoms. Co...
