The Core-level Binding Energies and the Structures of Nickel Complexes

Abstract The X-ray photoelectron spectra of thirty two nickel complexes were measured in order to examine the relation between the structures and the core-level binding energies of the complexes. The differences between the energies of Ni(2p) and Ni(3p) electrons for the complexes with an octahedral structure were about 1 eV larger than for those with a square planar one.
