Systematic studies of hexanuclear {MIII4LnIII2} complexes (M = Fe, Ga; Ln = Er, Ho): structures, magnetic properties and SMM behavior

“…[2][3][4] Therefore, the synthesis and characterization of high-nuclearity 3d-4f SMMs have attracted intensive attention in recent years. [5][6][7][8][9] Although many studies on 4f-4f or 3d-3d interactions have been reported, [10][11][12][13][14][15][16][17] research on 3d-4f exchange interactions is less developed. [18][19][20][21][22][23][24] Furthermore, according to the model of free-ion electron densities for all Ln III ions, the shape of the 4f electron density for the Dy III ion is oblate, while that for Er III is prolate.…”

Advances in the lanthanide metallosupramolecular chemistry of the cucurbit[n]urils

“…Apart from the unique spectroscopic and magnetic properties, the lanthanides and their derivatives have numerous applications, including as NMR imaging agents [3,4], in optoelectronics applications [5], as luminescent materials (including probes in biology and medicine) [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19], as new magnetic materials [20,21], as metal organic frameworks [22,23], as catalysts [24][25][26][27][28][29], and as vehicles for drug delivery in medicine [30,31]. Moreover, lanthanide species have been demonstrated be effective pharmaceuticals for the treatment of various diseases [32][33][34][35].…”

A UV-absorber bismuth(iii)-N-methyldiethanolamine complex as a low-temperature precursor for bismuth-based oxide thin films

“…13, 16,24,28 The complex contains Bi(III), a d 10 element, where ligand eld excited states are not possible. Charge transfer (CT) transitions in this complex may occur from a molecular orbital with a predominantly metal-like (M) character to another one with a ligand-like (L) character, exhibiting photoreactivity promoted by MLCT transitions.…”

“…The bond between the nitrogen and the metallic centre incorporates new functionalities into these types of molecules, such as photosensitivity. 14,16 A metal complex between Bi(III) and an alkanolamine, Nmethyldiethanolamine, is formed in solution and studied in this work. This complex presents primary bonds, Bi-O, Bi-N, and longer Bi-O-bonds, which can lead to the association of the monomer units.…”

“…Alkanolamines are exible co-ligands that can bind to a large range of metals. 16 Coordination occurs through N-donors and O or OH groups, and can lead to two types of molecules; simple compounds, where the hydroxyl groups of the alkanolamine are bonded to the metal cation, and cyclic compounds, where both the hydroxylic and the amino groups are bonded to the metal. The bond between the nitrogen and the metallic centre incorporates new functionalities into these types of molecules, such as photosensitivity.…”
