X-ray K-absorption studies of some schiff base copper oomplexes

770-771The chemical shifts and widths of copper K-edges are reported for some schiffbase copper complexes by means of X-ray absorption spectroscopy in which a Cauchris type bend spectrograph has been utilized. The metal-ligand distances have been computed using Levy's method. The results are examined to understand the nature of metal-ligand bonding. The observed linear relationships between chemical shifts (E, eV) and bond distance] (A) and edge width and metal-ligand electronegative differences have been interpreted in terms of changes in the degree of covalency of the metal-ligand bonding in the synthesised copper complexes

Ligand exchange equilibria of metal complexes-I: Ligand exchange of metal dithizonates with ɑ-benzoin oxime in chloroform

333-334Ligand exchange reactions between dithizonates of Ag+, Tl+, Cd2+, Zn2+, Cu2+, Ni2+, Co2+, Pd2+, Pb2+, Bi3+ and In3+ with ɑ-benzoin oxime in chloroform have been studied spectrophotometrically. From the exchange constants so determined the extraction constants of metal-ɑ-benzoin oximates have been calculated
