“…Establishing the values of Ln-S bond-valence parameters (R Ln-S ) seems useful because the Ln have a rich chemistry with S-donor ligands (thiolates, dithiocarbamates;Nief, 1998;Aspinall, 2001;Shen & Yao, 2002). Nevertheless, the number of molecular structures deposited in the Cambridge Structural Database is limited.…”

Ln-O and Ln-N bond-valence parameters have been computed in coordination complexes for lanthanides (Ln) at oxidation states other than +3 (Ce(IV), Sm(II), Eu(II) and Yb(II)). Moreover, Ln-Cl, Ln-S and Ln-C(pi-bonded) bond-valence parameters are presented, as calculated for coordination compounds. In general, the bond-valence parameters decrease in the order Ln-O > Ln-C > Ln-N > Ln-Cl > Ln-S. It has been found that the values of bond-valence parameters decrease with increasing lanthanide atomic number for coordination compounds. As expected, the values of lanthanide-oxygen and lanthanide-nitrogen bond-valence parameters diminish with increasing lanthanide oxidation state. Several examples are given where the total valence of the lanthanide ion is apparently incorrectly assigned, as well as cases where bond-valence method calculations confirm the doubtful oxidation state assignment.

“…Several radiopharmaceutical complexes have been described with dithiocarbamates, with indium-113m (Abram et al, 1985), copper-62 (Matsumoto et al, 1990), bismuth-212 (Parks et al, 1992), technetium-99m (Pasqualini et al, 1994), and rhenium-188 (Boschi et al, 2004). Moreover, rare earth complexes with dithiocarbamates have been the subject of an abundant literature and their structures have been extensively discussed (Nief, 1998;Cotton, 2004;Hitchcock et al, 2004;Regulacio et al, 2005). Reaction of yttrium and lanthanides with dithiocarbamates can result in ternary neutral complexes or quaternary anionic complexes.…”

Mixed-ligand complexes of yttrium-90 dialkyldithiocarbamates with 1,10-phenanthroline as a possible agent for therapy of hepatocellular carcinoma

Yttrium-90 is a radioelement which has found wide use in targeted radionuclide therapy because of its attractive physical and chemical properties. Radioembolisation of hepatocellular carcinoma with radiolabelled Lipiodol is a method of choice. We have synthesised a series of alkyldithiocarbamate yttrium complexes, easily extracted into Lipiodol due to their high lipophilicity. Among the prepared series, a new radioconjugate, which is stable over an extended period of time, has been prepared, and could represent a potential treatment procedure for hepatocellular carcinoma.

“…Since rare earth elements can be considered as hard ions and phosphorus as soft, phosphorus-containing moieties are not generally considered to be good ligands for these metals. Regardless, rare earth complexes with phosphorus-based donor ligands have gained increasing attention over the past two decades [92,93]. Although still scarce, a handful of studies on such compounds have been reported -the results from this work are presented below.…”

The research field surrounding rare earth pincer complexes has reached a stage where a comprehensive review about the reactivity and catalytic behavior of these species is justified. In this contribution, we begin with a brief introduction on common strategies for the preparation of rare earth pincer complexes, continuing with a section devoted to the versatile reactivity observed for this class of compound. Thereafter, several types of compounds are discussed, including extremely reactive hydrides, cationic species, and intriguing scandium imido complexes. Finally, the last portion of this chapter sums up the hitherto reported catalytic studies, including discussions on ring-opening polymerization of cyclic esters, polymerization of olefins and hydroamination reactions, as well as several examples of more infrequently encountered catalytic processes.
