On the K-absorption edge studies of copper in some nitrogen ligand complexes

Abstract

The X-ray K-absorption edges of copper in the nitrogen ligand complexes Cu(py)2Cl2, Cu(bipy)Cl2, Cu(bipy)(NO3)2, Cu(bipy)(AcO)2 and Cu(phen)Cl2 have been recorded using a 40 cm bent crystal spectrograph. The absorption edge shift and edge width have been discussed in terms of the effective nuclear charge and the nature of the ligand, and found consistent with other existing theories. The radii of first coordination sphere have been calculated in different compounds using Levy's method (1965).
