Pair distribution functions, D(r), of (a) AFI-[Zn(Im)1.68(bIm)0.32] and ag AFI-[Zn(Im)1.68(bIm)0.32], and (b) CAN-[Zn(Im)1.73(bIm)0.27] and agCAN-[Zn(Im)1.55(bIm)0.45], and the inserts assign PDF peaks to the main short atom-atom distances in the structure. Zn, blue; C, dark green; N dark yellow; H, omitted.
