Catalyst	CNSXRD	CNEXAFS	R SXRD [Å]	R EXAFS [Å]	E not [eV]
Fe-ZSM-5	4.7(5)	5.3(6)	1.71(5)	1.79(3)	0.7
Zn-ZSM-5	4.8(2)	5.2(2)	2.11(2)	2.07(1)	3.4
Ag-ZSM-5	2.7(2)	2.7(3)	2.19(3)	2.33(3)	0.1

^aEstimated standard deviation (ESD) are presented in brackets; CN stands for coordination number; R represents derived atomic distance (see ESI).

^bThe calculation of CN^SXRD is based on averaging the total coordination number of each transition metal site multiple by their occupancy.

^c R ^SXRD is the occupancy weighted bond length of each M–O.
