Structure and magnetic properties of two new lanthanide complexes with the 1-((E)-2-pyridinylmethylidene)semicarbazone ligand

High-Coordinate Mononuclear Ln(III) Complexes: Synthetic Strategies and Magnetic Properties

“…The Dy(III) derivative showed step-like features signifying QTM at the level crossing while the Tb derivative did not. 35)) (Figure 19) [56]. The two ligands provided a 4N,2O coordination environment while the remaining four sites e occupied by the nitrate ions.…”

“…Semicarbazone based ligands have been widely used in coordination chemistry including in the formation of lanthanide complexes. Nunes and co-workers used a semicarbazone based Schiff base ligand 1-((E)-2-pyridinylmethylidene)semicarbazone), Hscpy, to prepare mononuclear complexes, [Ln(Hscpy) 2 (NO 3 ) 2 ]NO 3 •MeOH (Ln(III) = Gd (34) and Tb (35)) (Figure19)[56]. etochemistry 2020, 6, x FOR PEER REVIEW 17 of 29…”

“…There are various uses of lanthanides for an array of applications across many scientific spheres. The broader spectrum of applications for this series encapsulates magnetic studies [6,7], nuclear chemistry [8], catalysis [9,10], radio-therapy [11,12], ceramic's [13,14] and many others. Europium ions are extensively utilised in photoluminescence research, particularly as a potential photo-emissive layer in the edifice of optoelectronic devices [15][16][17].…”

Five Dinuclear Lanthanide Complexes Based on 2,4-dimethylbenzoic Acid and 5,5′-dimethy-2,2′-bipyridine: Crystal Structures, Thermal Behaviour and Luminescent Property

“…Therefore, lanthanide ions with special electronic structure are preferred in the selection of metal ions, which makes the complexes have excellent optical properties and can be used in the fields of luminescent materials, biological imaging, biological response probes and sensors ( Liu et al, 2014a ; Abbas et al, 2017 ; Gu et al, 2018 ). Moreover, lanthanide ions as metal center ions have the advantages of large radius, high coordination number and diverse coordination environment ( Soek et al, 2019 ). In addition to the selection of lanthanide ions, the suitable ligands are also very critical.…”
