Transition Metal Cluster and Polygadolinium Compounds as a New Paradigm For High Attenuation and/or Relaxivity in Contrast Media Design: Crashing The Molecular r1 = 100 Barrier

Hydrolytic Synthesis and Structural Characterization of Lanthanide Hydroxide Clusters Supported by Nicotinic Acid

“…[12][13][14] Lanthanide hydroxide clusters have also been proposed as new paradigms of contrast-enhancing agents in biomedical imaging. 15,16 More recently, fixation of atmospheric CO 2 by lanthanide hydroxides has been observed, [17][18][19] which carries significant ramifications from the environmental viewpoint. It is thus reasonable to predict that the research activities of lanthanide hydroxide clusters will continue to grow with high possibility of finding interesting materials with useful applications that have not yet been realized or even contemplated.…”

New Hexanuclear Niobium Cluster Compounds with Pyridine and N‐Methylpyrrolidone Ligands: [Nb6Cl12(Pyr)6][AlCl4]2 and [Nb6Cl12(NMP)6][GaCl4]2

“…Cluster excision and subsequent ligand exchange reactions gives rise to a plethora of new compounds. [2][3][4][5][6][7][8][9][10][11][12][13][14] Recent investigations on early transition metal cluster compounds focus on using them as catalysts, [15,16] luminescent materials, [17,18] sensors, [19] medical X-ray contrast agents, [20,21] or as precursors for elaboration of nano-cluster materials. [22] For all such investigations on possible applications the knowledge about the synthesis, properties, and structures of as many as possible different compounds is essential.…”

Gd26Cluster Consisting of Distorted Cubane Cores: Synthesis, Structure and Heterogeneous Catalytic Epoxidation of Olefins

“…In this context, oxo, hydroxo and fluorido bridged lanthanide clusters are worthy of note. [24][25][26][27][28][29][30][31] It has been well documented that lanthanide compounds have relevance to homogeneous catalysis, [32] molecule-based magnetic materials, [33] contrast agents for magnetic resonance imaging [34] and fixation media for essential atmospheric gases. [35] In the field of oxidative catalytic transformations, [36] epoxidation of alkenes is a key chemical process in biology, [37] synthetic organic chemistry and in chemical industry.…”
