(a) Displacement ellipsoid plots of α-FOX-7 at 80, 164, 280 and 360 K (50% probability level). (b) Four molecules in the monoclinic unit cell (P21/n) of α-FOX-7 at 80 K. (c) The wave-shaped layer-type packing of α-FOX-7 at 80 K with the interplanar angle of adjacent molecules, θ = 140.10 (2)°, viewed along the a axis. (d) Intra- and intermolecular O—H⋯O hydrogen bonds stabilizing the layer-type structure of α-FOX-7 at 80 K (magenta connecting lines). Note that atoms O21 and O22 having fewer interactions are oriented out of the mean molecular plane. |
