Figure Lengend Snippet: Graphical representation of the crystal structure of Zr/Ce_TTp: (a) the node; (b) portion of the packing visualized along one of the crystallographic axes. For clarity, (i) an ideal crystal structure was employed, disregarding the missing linker defects and removing the S/C–H vicariance; (ii) the clathrated DMF molecules hosted in the pores were omitted. Element colour code: C, grey; H, light grey; O, red; S, yellow; Zr/Ce, light blue. The crystal structure of Zr_TTp is not distinguishable to the eye from that of Zr/Ce_TTp.

Figure Lengend Snippet: EXAFS fitting results shown in the direct space (a and b) and reciprocal space (c and d) for Zr_TTp (a and c) and Zr/Ce_TTp (b and d). The observed data are represented by red dots, and the result of the fit is shown in black and dark green for Zr_TTp and Zr/Ce_TTp, respectively. Fitting windows are shown in cyan. Data are shown by using a k -weight of 2.
