Figure 1
The structure of (I) showing 50% probability displacement ellipsoids. Note that the PF6− anion interacts with oxythiamine through a bifurcated hydrogen bond, C2—H⋯F3 and C2—H⋯F4, and close contacts, F3⋯pyrimidine and F4⋯pyrimidine. Broken lines denote hydrogen bonds. H atoms are drawn as small spheres of arbitrary radii. |
