From dinuclear to two-dimensional Dy(iii) complexes: single crystal–single crystal transformation and single-molecule magnetic behavior

Abstract

Regulating the magnetic property through structual transformation and multifunctional magnetic bistable materials attract increasing interst in the research area of molecular magnets. Herein, we have obtained a two-dimensional Dy3+ metal-organic...

Single molecule magnet features in luminescent lanthanide coordination polymers with heptacoordinate Dy/Yb(iii) ions as nodes

“…34 Lastly, stabilizing their structures and SMM behavior helps in surface deposition and device preparation of SMMs. 34 Although several Ln coordination polymers with SMM behavior have been reported before, [34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52] Ln coordination polymers with SMM behavior constructed from seven-coordinated Ln ions are still scarce. [53][54][55][56][57] Besides the SMM behavior, bright luminescence varying from visible to near-infrared regions can be found in Ln complexes.…”

Influence of lattice water molecules on the magnetization dynamics of binuclear dysprosium(iii) compounds: insights from magnetic andab initiocalculations

“…The values of M under low magnetic fields rise sharply as the applied magnetic field (H) is amplified before increasing slowly at high fields, finally achieving 10.48m B for 1 and 10.46m B for 2 at 2 K, respectively, which are close to the expected value of 10m B two Dy III ions in a pure m J = |AE15/2i ground state. [34][35][36] Notably, magnetic hysteresis measurements were performed on 1 and 2 at a sweep rate of 100 Oe min À1 . 1 does not display the hysteresis loop at 2.0 K due to the presence of a relatively fast zero-field relaxation, while 2 displays a butterfly-shaped hysteresis with openings up to 5.0 K at H a 0, suggesting the existence of magnetic blocking (Fig.…”

Single-ion magnetism behaviors in lanthanide(iii) based coordination frameworks

“…Diacylhydrazone was used as the bridging ligand to create 2D structures of compound 14 . 74 Phosphonoacetic acid and a carbohydrazide ligand can also be utilized as a linker to make compounds 15 and 16 75 and compounds 18 and 19 respectively. 77 The temperature dependence of the dc susceptibility of compound 16 shows antiferromagnetic couplings among Er( iii ) atoms, while ferromagnetic interaction was observed in compound 15 at low temperature.…”
