Planar chiral [2.2]paracyclophanyl-based boron fluoride complexes: synthesis, crystal structure and photophysical properties

Planar chiral [2.2]paracyclophanyl-based boron fluoride complexes (3a-3d) were designed and facile synthesized. X-ray structure study, theoretical calculations and CD spectra reveal the intense emission and planar chiral structure of these...

Tin(iv) fluoride complexes with neutral phosphine coordination and comparisons with hard N- and O-donor ligands

Abstraction of fluoride from tin(iv) fluoride complexes bearing neutral phosphine ligands yields mono, di- and tri-fluoride complexes with retention of two phosphines, whereas with neutral O- and N-donor trifluoride cations, dications are formed.

Neutral and cationic germanium(IV) fluoride complexes with phosphine coordination – synthesis, spectroscopy and structures

The neutral complexes, trans-[GeF4(PiPr3)2], [GeF4(2-L)] (L = CH3C(CH2PPh2)3 or P(CH2CH2PPh2)3) are obtained from [GeF4(MeCN)2] and the ligand in CH2Cl2. Treatment of [GeF4(PMe3)2] with n equivalents of TMSOTf (Me3SiO3SCF3) leads to...
