Abstract

Mössbauer spectra and X-ray diffraction patterns of [Fe(bpy)3]2+ synthesized in supercages of zeolite Y reveal three interesting features of this system: first, the spectra show no evidence of steric distortion of the complex, secondly, special pretreatment of zeolite (ion exchange with La3+ and a subsequent heat treatment in order to block the small cavities) can stimulate the complex formation in the zeolite, and thirdly, despite the fact that the large complex cannot be introduced directly into the Y zeolite, it can be removed (at least partially) by cation exchange, by taking advantage of the dynamic feature of complex equilibrium in the presence of a ligand-eliminating process.
