Abstract: | Summary Copper chloride methylpyrazole complexes have been studied and their quantitative composition and physicalchemical properties determined. On the basis of spectroscopic, electron paramagnetic resonance (c.p.r.) and magnetic studies, the structures of the complexes occurring in solids and the ethanol solutions are discussed. Four- and six-coordinate Cu-pyrazole complexes have been distinguished and the bridging properties of 3,5-demethylpyrazole ligand rationalized. |
