EPR OF COPPER(II) CHLORIDE COMPLEXES WITH DIPHOSPHINE DIOXIDES

Article abstract of DOI:10.1007/BF00965421

Stepwise formation of copper(II) chloride complexes with diphosphine dioxides has been studied using paramagnetic resonance.It was found that in complexes with a copper:ligand composition of 1:1 substituents have little effect on parameters of the anisotropic EPR spectra.The spectra of complexes with a metal:ligand composition of 1:2 are considerably more sensitive to the introduction of substituents; this is explained by sterically dependent differences in the structure of the complexes.The possibility of trisligand complexed being formed is evidently largely determined by the size of the groups on the phosphorus atoms.
