Field-induced slow magnetic relaxation in chiral seven-coordinated mononuclear lanthanide complexes.
Four couples of enantiomerically pure chiral seven-coordinated mononuclear lanthanide complexes, [(L(OEt))Dy((R,R)-Salphen)](2)·3H(2)O (1, L(OEt) = [(Cp)Co(P(O)(OEt)(2))(3)], Cp = cyclopentadiene, Salphen = N,N'-1,2-diphenylethylenebis(salicylideneiminato) dianion), [(L(OEt))Dy((S,S)-Salphen)](2)·3H(2)O (2), [(L(OEt))Dy((R,R)-5-Cl-Salcy)]·CH(3)OH·1/8H(2)O (3, Salcy = N,N'-(1,2-cyclohexanediylet...
متن کاملField-induced slow relaxation of magnetization in dinuclear and trinuclear CoIII⋯MnIII complexes
Two new dinuclear, [Co(3EtO-L5)(m-CN)Mn(L4a)Cl] (1) and [Co(3EtO-L5)(m-CN)Mn(L4a)Br] (2), and two trinuclear [{Co(3EtO-L5)(m-CN)}2Mn(L4a)]I (3) and [{Co(3EtO-L5)(m-CN)}2Mn(L4a)](NO3) (4) complexes were prepared and thoroughly characterized (H23EtO-L5 1⁄4 N,N0-bis(3-ethoxy-2-hydroxybenzylidene)1,6-diamino-3-azahexane, L4a 1⁄4 N,N0-ethane-bis(salicylideneiminate)dianion). The crystal structures w...
متن کاملA series of 1D Dy(III) compound showing slow magnetic relaxation: synthesis, structure, and magnetic studies.
In this work, we present the synthesis, structure, and magnetic studies of three 1D homo-spin Dy(III) compounds in detail. For 1, one crystallography-independent Dy(III) site is contained and the coordination surrounding is a distorted square-antiprism geometry. Within 2, four crystallography-independent Dy(III) sites with largely distorted square-antiprism geometry are observed. As for 3, two ...
متن کاملHomochiral mononuclear Dy-Schiff base complexes showing field-induced double magnetic relaxation processes.
A pair of enantiopure mononuclear dysprosium/salen-type complexes (Et3NH)[Dy((R,R)/(S,S)-3-NO2salcy)2] (/), where 3-NO2salcyH2 represents N,N'-(1,2-cyclohexanediylethylene)bis(3-nitrosalicylideneiminato), are reported. The enantiomer contains two crystallographically independent dysprosium(iii) ions, each chelated by two enantiopure 3-NO2salcy(2-) ligands forming a [DyN4O4] core. Detailed magne...
متن کاملSlow Magnetic Relaxation of Lanthanide(III) Complexes with a Helical Ligand
Isostructural Ln(III) mononuclear complexes [Ln(NO3)2L]PF6·MeCN (Ln = Nd, Tb, or Dy; L denotes a helical hexa-dentate ligand) were synthesized, and their slow magnetic relaxation behavior was investigated. In these complexes, oblate-type Ln(III) ions are located in an axially stressed ligand field with two nitrate anions, and can exhibit single-molecule magnet (SMM) behavior. Field-induced SMM ...
