Аннотация: To design luminescent lanthanide complexes containing both p- and s-bonded antenna ligands in the coordination sphere, we synthesized 2,2'-bipyridine complexes of Nd, Tb and Gd with tri- and tetraphenyl substituted cyclopentadienyl ligands: [CpPh3LnCl2(bipy)(THF)] (CpPh3= 1,2,4-triphenylcyclopentadienyl, bipy = 2,2'-bipyridine) and [CpPh4LnCl2(bipy)(THF)] (CpPh4 = tetraphenylcyclopentadienyl). Their crystal structures were determined by X-ray diffraction analysis. Optical spectroscopic and crystallographic data indicate the presence of a ligand-to-ligand charge transfer state.

Ключевые слова: lanthanide complexes, Cp ligand, NIR luminescence, crystal structure, charge transfer state.
