✦ Synopsis

Edge shifts (1E ), effective nuclear charge (Z eff ) and % covalency for some copper(II) mixed-ligand complexes were determined by investigating the copper K-absorption edge using a Seifert x-ray generator and a 0.4 m Cauchois-type bent crystal transmission spectrograph. The shift values are suggestive of a parabolic dependence on Z eff of copper. Using the method of least squares, an expression 1E = a + b(Z eff ) + c(Z eff ) 2 was found to hold good for the dependence of 1E on Z eff in the case of the complexes studied.

A new application of Wiener indices in estimating x-ray K-absorption parameters is described. X-ray K-absorption parameters were correlated with Wiener indices. Some copper(II) and cobalt(II) complexes of pyrazolin-5-ones as ligand were used to establish this type of correlation. The chemical shift
