Cu K-Edge XAS Study of the [Cu_2(μ-O)_2] Core: Direct Experimental Evidence for the Presence of Cu(Ⅲ)

摘要

In the course of this work, structural features suggestive of Cu(Ⅲ) have been verified by EXAFS and coupled to identifiable features in the Cu K-edge-i.e., a shift in the edge energy and a pre-edge at 8981 + -0.4 eV. This work therefore provides a foundation for the systematic description of Cu(Ⅲ) sites by XAS.
