Journal ArticleDOI
Coordination of 2,2'-bipyridyl and 1,10-phenanthroline to substituted ytterbocenes: An experimental investigation of spin coupling in lanthanide complexes
TL;DR: In this article, an electron exchange model for spin coupling between Yb(III), with electron configuration 4f13, and the single unpaired electron in the bipyridyl radical anion was presented, based on comparison with the iodide salt [(Me5C5)2YbIII(bipy0)]+[I]-.
Journal ArticleDOI
Electron-transfer reactions of divalent ytterbium metallocenes. Synthesis of the series [(Me5C5)2Yb]2[.mu.-E] (E = oxygen, sulfur, selenium, or tellurium) and crystal structure of [(Me5C5)2Yb]2[.mu.-Se]
Journal ArticleDOI
Preparation of Coordination Compounds of Cp*2Yb with Heterocyclic Nitrogen Bases: Examples of Antiferromagnetic Exchange Coupling across Bridging Ligands
TL;DR: The 1:1 adducts with phthalazine and azobenzene and the 1:2 adduct with pyridazine are soluble in toluene, from which they may be isolated by crystallization.
Journal ArticleDOI
Heptadentate ligands for the lanthanides. The first structurally characterized example of a lanthanide heptadentate ligand complex: [tris(3-aza-4-methyl-6-oxohept-4-en-1-yl)amine]ytterbium(III)
Journal ArticleDOI
Electron-transfer chemistry of (Me5C5)2Yb: cleavage of diorganoperoxide and related chalcogenides to give (Me5C5)2Yb(ER)(L) (E = O, S, Se, or Te; L = a Lewis base). Crystal structure of (Me5C5)2Yb(TePh)(NH3)
TL;DR: In this paper, the divalent metallocenes of ytterbium (Me/sub 5/C/Sub 5//sub 2/)(OEt/sub 2/) react with molecules of the type REER to give the trivalent ybium complexes, where L is a phenyl or substituted phenyl group.
