Terbium Polyoxometalate Organic Complexes: Correlation of Structure with Luminescence Properties

Polyoxometalate-Supported Lanthanoid Single-Molecule Magnets

“…This includes numerous lanthanoid complexes with POM ligands (Ln-POMs), which are of interest for their magnetic, luminescent, catalytic, and electronic properties. [29][30][31][32][33] Ln-POM Single-Molecule Magnets Inorganic POMs offer several advantages over organic species as supporting ligands for Ln-SMMs. Due to the steric bulk and intrinsic diamagnetism of the oxidised forms, they can ensure good magnetic insulation of the lanthanoid ions in neighbouring B molecules, minimising intermolecular interactions that can give rise to unwanted quantum tunnelling and loss of magnetisation.…”

The Syntheses, Structures, and Magnetic Properties of Four 2D Lanthanide(III)‐naphthalenedicarboxylic Complexes

“…[8,9] The 1,4-naphthalened-acidity-dependent types and coordination modes: HNDC 1-with μ-η 1 :η 1 and NDC 2-with μ-η 1 :η 2 :η 1 :η 2 . The 3D supramolecular networks of 1-4 are mainly controlled by hydrogen bonds interactions.…”

“…The rational design and construction of lanthanide-organic frameworks (LnOFs) based on the assembly of lanthanide ions and organic ligands have been attracting increasing interest in recent years because they show diverse structural architectures and generally possess characteristic luminescent emission and a large anisotropic magnetic moment, [1][2][3] resulting from the unique nature of Ln III ions with large radii, high coordination numbers, flexible coordination arrangements, and a large number of spins and strong spin-orbit coupling. [4,5] Besides the nature of the central metal atoms, the nature and the linking modes of the bridging ligand also play a vital role in the functional Ln-based complexes, which can act as magnetic mediators and luminescent sensitizers via the "antenna effect".…”

Synthesis and Characterization of 8-Yttrium(III)-Containing 81-Tungsto-8-Arsenate(III), [Y8(CH3COO)(H2O)18(As2W19O68)4(W2O6)2(WO4)]43−

“…Most of the OPEN ACCESS work in this area has been focused on 3d transition metal-containing derivatives [11][12][13][14][15][16][17]. However, also the area of rare earths-containing POMs has undergone a significant expansion in recent years [18][19][20][21][22][23]. Lanthanide ions usually have larger coordination numbers (8,9 or more) than d-block metal ions, and exhibit various coordination geometries [24].…”

“…In addition, the larger size of these lanthanide ions usually restricts their full incorporation into the lacunary POM sites. Such coordination behavior renders lanthanide ions frequently as linkers of two or more lacunary POM units, forming large structures [18][19][20][21][22][23][25][26][27]. Yttrium is formally not a lanthanide, but can be considered as a pseudolanthanide, due to its comparable size and coordination number.…”
