Figure 3

(a) Molecular structures determined by single‐crystal XRD analysis at 298 K for FMesB‐Cz and at 180 K for FMesB‐Ac and FMesB‐Ptz. Thermal ellipsoids are drawn at the 50 % probability level. Hydrogen atoms have been omitted for clarity. Selected bond lengths [Å] for FMesB‐Cz: B1−C1 1.562(3), B1−C12 1.567(3), B1−C13 1.580(3); for FMesB‐Ac: B1−C1 1.553(3), B1−C12 1.560(3), B1−C13 1.584(3); for FMesB‐Ptz: B1−C1 1.562(2), B1−C12 1.561(2), B1−C13 1.581(2). The pictures show the crystals under a UV lamp. (b) Optimised geometries and AIM analysis of FMesB‐Cz, FMesB‐Ac and FMesB‐Ptz, showing the B⋅⋅⋅F bond paths (purple lines) and BCPs (red points).
