Additionally, we managed to obtain and analyze SC-XRD data for meta-stable Ar-SF4Cl compounds 18 and 19 -the starting materials for 8 and 15, respectively (Figure ). When compared alongside the only other two Ar-SF4Cl compounds reported in the solid state, 24 they seem to also follow this trend of increasing S-CAr distance with electron-withdrawing effect of the arene (concomitant with a decrease in S-Cl distance).
