Nuclear quadrupole resonance and stereochemistry. Part 7. The axial and equatorial chlorine atoms in octahedral complexes of antimony pentachloride, SbCl5L (L = donor ligand)
Abstract
Chlorine-35 and 121,123Sb n.q.r. frequencies and their temperature dependencies for various octahedral complexes of antimony pentachloride, SbCl5L (L = donor ligand), are reported. Assignments of 35Cl resonances to axial or equatorial chlorine atoms of the SbCl5 fragment have been possible in some cases. There are no apparent systematic differences between the frequencies of the axial or equatorial chlorine atoms, such differences as there are being masked by crystal-field effects of similar magnitude.
