Slow magnetic relaxation in cobalt N-heterocyclic carbene complexes

Dalton Transactions, 2020
The combined experimental and theoretical investigation of the magnetic properties of [Co(CH2SiMe3)2(IPr)] (1), [CoCl2(IMes)2] (2) revealed a large easy plane anisotropy for 1 and a moderate easy axis anisotropy for 2.

Lanthanide Based Layer Type Two Dimensional Coordination Polymers Featuring Slow Magnetic Relaxation, Magnetocaloric Effect and Proton Conductivity.

Chemistry - An Asian Journal, 2019
Three lanthanide-based two dimensional (2D) coordination polymers (CPs), [Ln(L)(H2O)2]n, {H3L= (HO)2P(O)CH2CO2H; Ln= Dy3+ (CP 1) , Er3+ (CP 2)} and [{Gd2(L)2(H2O)3}.H2O]n, (CP 3) were hydrothermally synthesized using phosphonoacetic acid as a linker ...

Slow magnetization relaxation and reversal in magnetic thin films

Journal of Physics: Condensed Matter, 2008
The slow magnetization dynamics in magnetic thin films has been investigated in this paper. It is shown that the experimental results of the time-dependent magnetization can be well described by the extended exponential function, exp(−(t/τ)β) with β>0, in a number of thin film systems.

Slow Magnetic Relaxation of Co(II) Single Chains Embedded within Metal-Organic Superstructures.

Inorganic Chemistry, 2019
Two coordination polymers of the type Co(BPDC)(N-ox), with BPDC being 4,4'-biphenyldicarboxylate and N-ox being pyridine N-oxide (PNO) or isoquinoline N-oxide (IQNO), have been synthesized and characterized.

3D LnIII-MOFs: displaying slow magnetic relaxation and highly sensitive luminescence sensing of alkylamines

CrysteEngComm, 2019
Six isomorphous Ln-based MOFs with 3D structures have been synthesized under solvothermal conditions. Dy-MOF (5) shows slow magnetic relaxation behaviors. Eu-MOF (3) can serve as a recyclable sensor towards alkylamines in water systems.

Magnetic anisotropy and slow magnetic relaxation processes of cobalt(ii)-pseudohalide complexes.

Dalton Transactions, 2019
Three mononuclear six-coordinate Co(ii)-pseudohalide complexes [Co(L)X2] with two N-donor pseudohalido coligands occupying the cis-positions (X = NCS- (1), NCSe- (2) or N(CN)2- (3)), and a five-coordinate complex [Co(L)(NCO)][B(C6H5)4] (4) [L = 1,4,7,10 ...

Capping Ligand Perturbed Slow Magnetic Relaxation in Dysprosium Single‐Ion Magnets

Chemistry – A European Journal, 2011
AbstractSingle‐ion magnets 1 and 2 and their diamagnetic analogues 3 and 4 for magnetic‐site dilution were obtained through substitution of the coordinated water molecules of [Ln(TTA)3(H2O)2] (Ln=Dy (1, 2), Y (3, 4); TTA=4,4,4‐trifluoro‐1‐(2‐thienyl)‐1,3‐butanedionate) by 2,2′‐bipyridine (1, 3) and 1,10‐phenanthroline (2, 4) capping ligands.

Highly Reduced Double-Decker Single-Molecule Magnets Exhibiting Slow Magnetic Relaxation

Inorganic Chemistry, 2013
F64Pc2Ln (1Ln, Ln = Tb or Lu) represent the first halogenated phthalocyanine double-decker lanthanide complexes, and 1Tb exhibits single-molecule magnet properties as revealed by solid-state magnetometry. The fluorine substituents of the phthalocyanine rings have a dramatic effect on the redox properties of the F64Pc2Ln complexes, namely, a ...

Slow magnetic relaxation in a high-spin pentacoordinate Fe(iii) complex.

Chemical Communications, 2019
A mononuclear pentacoordinate iron(iii) complex shows slow magnetic relaxation with three relaxation channels. The high-frequency relaxation time of the order of microseconds is prolonged on cooling in accordance with the direct and Raman processes.

A tetranuclear cobalt(ii) chain with slow magnetization relaxation

Dalton Transactions, 2010
A solvothermally derived tetranuclear cobalt(II) complex, [Co(4)(phen)(4)Cl(8)] (phen = phenanthroline), featuring a zig-zag backbone of {Co(μ(2)-Cl)(2)Co} planes, exhibits ferromagnetic exchange and slow relaxation of the magnetization and represents the first Co SMM with a linear core structure.
