Heteroleptic lanthanide terphenyl/tris(pyrazolyl)borate compounds of ytterbium

The synthesis and structural characterization of the two novel unsolvated heteroleptic ytterbium compounds DanipYb(TpMe,Me)Cl (1) and DanipYb(TpMe,Me)CH2SiMe3 (2) by simple salt metathesis reaction is reported [Danip = 2,6-di(o-anisol)phenyl); TpMe,Me = hydrotris(3,5-dimethyl-pyrazolyl)borate]. In the molecular structure of 2 a flexible bonding mode of the donor-functionalized terphenylic ligand is observed.

The synthesis and X-ray crystal structure determination of two heteroleptic compounds of ytterbium is reported, based on a donor-functionalized terphenyl moiety vis-à-vis a tris(pyrazolyl)borate ligand. Shown is molecular structure of the solvent-free chloro derivative.Figure optionsDownload as PowerPoint slide
