Bonding in Copper (II) Chelates: Solvent Effects in their Visible Absorption

Complex formation between copper ethylacetoacetate and polyoxyethylene glycol

Spin exchange between particles with an anisotropic spin-density distribution

The complex formation between copper (II) dipivaloylmethanate Cu(dpm)2 and copper (II) hexafluoroacetylacetonate Cu(hfacac)2 and polyoxypropylene glycols (PPG) with molecular masses of 200 and 1050 was studied by spectrophotometry in the visible region and by ESR. The compositions of the complexes (1∶1) and the thermodynamic parameters of complex formation were determined. In complexing power Cu(dpm)2 is inferior to Cu(hfacac)2. Complex formation between Cu(hfacac)2 and PPG is accompanied by structural changes in the β-diketonate.

Complex formation between copper β-diketonates and polyoxypropylene glycols

Effect of complex formation with electron-donor molecules on ESR spectra and on electron structure of copper (II) acetylacetonates

Exchange broadening of ESR lines in dilute solutions containing two types of paramagnetic particles

Study of complexes of phenylisocyanate and methanol with copper (II) BIS(3-ethylacetylacetonate) by means of ESR and optical spectroscopy
