Synthesis and Structural Characterization of Tetra‐ and Pentanuclear Lanthanide Hydroxido Clusters

Rare‐Earth Metal Oxo/Hydroxo Clusters – Synthesis, Structures, and Applications

“…2 ] (Ln = Yb, Lu) were obtained. [34] In a similar way the tetranuclear complexes [Er 4 (Ph 2 acac) 6 -(O-btd) 4 4 (O-btd) 6 (OH) 2 ] (O-btd = 4-hydroxy-2,1,3-benzothiadiazolate) were synthesized. [55] Obviously, the choice of the right co-ligand is crucial for obtaining the pentanuclear structural motif.…”

Luminescent Polymeric Dispersions and Films Based on Oligonuclear Lanthanide Clusters

“…[Eu 5 (OH) 5 (Ph 2 acac) 10 ] (2) was synthesized using a modified literature procedure. [18] To a stirred solution of KOtBu (1.144 g, 9.89 mmol, 3 eq.) in 20 mL of methanol, HPh 2 acac (1.48 g, 6.59 mmol, 2 eq.)…”

“…The latter pathway for example involves the reaction of [LnCl 3 Á(n H 2 O)] (n ¼ 6, 7) with a suitable ligand in the presence of a base to give nanoscaled cluster compounds. [10,[15][16][17][18] In general, the cage dimensions depend on the sizes of both the lanthanide(III) ion (Ln 3þ ) and the ligand. In this context, we and others have reported the synthesis and structure of pyramidally shaped pentanuclear lanthanide clusters, [Ln 5 (OH) 5 The successful embedding of different amounts and types of hydrophobic rare earth clusters (Ln ¼ Y, Pr, Eu, Sm, Nd) in various polymer matrices via miniemulsion polymerization is presented.…”

Synthesis and characterization of an unprecedented 3D lanthanide coordination polymer assembled by cubane-like clusters and a flexible V-shaped dicarboxylate ligand

“…Recently, some interesting polynuclear lanthanide-hydroxo clusters have been reported, such as the tetranuclear clusters [1][2][3], pentanuclear clusters [4][5], hexanuclear clusters [6][7][8], heptanuclear clusters [9][10], and higher-nuclear clusters [11][12]. Most of these polylanthanide hydroxo complexes have been synthesized by a selfassembly process, in which metals as nodes are connected by carboxylate ligands as linkers to form varying structures with different shapes and sizes, topologies, and functionalities.…”
