Kh. Reddy et Y. Lingappa, SYNTHESIS AND SPECTRAL STUDIES OF NOVEL COPPER(II) CHELATES OF SULFUR-CONTAINING OXIMES, Transition metal chemistry, 19(5), 1994, pp. 487-490
Copper complexes of benzil-alpha-monoxime-2-iminoethanethiol (BMETH(2)
), benzil-alpha-monoxime-2-iminobenzenethiol (BMBTH(2)), benzil-alpha-
monoximethiosemicarbazone (BMTH(2)) and benzil-alpha-monoximesemicarba
zone (BMSH(2)) were synthesized and characterized by physicochemical a
nd spectroscopic measurements. The molar conductivities show that all
of the complexes are nonelectrolytes. The i.r. spectra suggest that th
e 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 coord
ination 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 d
imeric structures.
