Field-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 کاملField-induced slow relaxation of magnetization in a pentacoordinate Co(II) compound [Co(phen)(DMSO)Cl2].
The static and dynamic magnetic properties of a pentacoordinate [Co(phen)(DMSO)Cl2] compound (phen = 1,10'-phenanthroline, DMSO = dimethyl sulfoxide) were thoroughly studied by experimental (SQUID magnetometry and HF-EPR spectroscopy) and theoretical methods (DFT and CASSCF calculations). It has been found from temperature/field-dependent magnetization measurements that the studied compound pos...
متن کاملField-induced slow relaxation of magnetization in a tetrahedral Co(II) complex with easy plane anisotropy.
The mononuclear Co(II) complex CoBr (dmph = 2,9-dimethyl-1,10-phenanthroline) was obtained and X-ray structurally characterized as a distorted tetrahedron environment that is responsible for the moderately strong positive anisotropy of high spin Co(II). In combination with variable-field magnetic susceptibility data at low temperature, high-field electron paramagnetic resonance (HF-EPR) spectro...
متن کاملNeodymium 1D systems: targeting new sources for field-induced slow magnetization relaxation.
Two non-isostructural homometallic 1D neodymium species displaying field-induced slow magnetization relaxations are presented together with theoretical studies. It is established that both systems are better described as organized 1D single molecule magnets (SMMs). Studies show great potential of Nd(III) ions to provide homometallic chains with slow magnetic relaxation.
متن کاملSlow magnetic relaxation of light lanthanide-based linear LnZn2 trinuclear complexes.
Four isostructural LnZn2 trinuclear complexes, [Ln(NO3){Zn(L)(SCN)}2] (H2L is a Schiff base ligand derived from o-vanillin and ethylenediamine), were synthesized, which include light lanthanide ions as spin carriers (Ln = Ce 1, Pr 2, Nd 3, and Sm 4). These complexes involve a linear Zn(ii)-Ln(iii)-Zn(ii) array, which leads to an axially stressed ligand field and can also cause single-moleluce m...
