Figure 1
The molecular structure of (I), showing the atomic numbering scheme. Displacement ellipsoids are drawn at the 30% probability level. N-Bound H atoms are shown as small spheres of arbitrary radii; all other H atoms have been omitted for clarity. Dashed lines indicate N—H⋯O hydrogen bonds. The BF4− anion is disordered over two orientations, with F-atom occupancies of 0.905 (3) (unprimed) and 0.095 (3) (primed). |
