X‐ray absorption studies have been performed on Cu(en)2+2 exchanged Y zeolite. The copper EXAFS shows that there is little change in the equatorial copper‐ligand bond lengths, but the XANES is indicative of axial distortions. Both the EXAFS and XANES can be interpreted to show that the complex remains intact upon exchange and that it is structurally and electronically similar to the bis(ethylenediamine) copper (II) complex in solutions.
