摘要：

Extended X-ray absorption fine structure confirms the substitution of Si by Fe in the framework of zeolite ZSM-5. Each framework Fe atom is coordinated to four oxygens with an Fe-O distance of 1.83 angstrom, and to four Si atoms in the second coordination shell: two at 3.2 angstrom and two at 3.38 angstrom from Fe, compared with an average Si-Si distance in silicalite of 3.1 angstrom. The distances between the framework Fe atom and some of the atoms in the template molecule are determined here for the first time.
