Abstract: | Summary Copper complexes of benzil- -monoxime-2-iminoethanethiol (BMETH2), benzil- -monoxime-2-iminobenzenethiol (BMBTH2), benzil- -monoximethiosemicarbazone (BMTH2) and benzil- -monoximesemicarbazone (BMSH2) were synthesized and characterized by physicochemical and spectroscopic measurements. The molar conductivities show that all of the complexes are nonelectrolytes. The i.r. spectra suggest that the ligands are tetradentate in all cases, whilst the electronic spectra suggest planar geometries for all the complexes. The calculated e.s.r. parameters show an axial dx
2 - y
2 ground state and suggest coordination through sulphur, in agreement with the i.r. results. In all of these complexes, the =N—;O group acts as a bridging function to give dimeric structures. |
