Figure 1
The asymmetric unit of (I), extended in order to complete the BPM molecule by symmetry [symmetry code: (i) 2 − x, −y, −z], showing the atom-labelling scheme. Displacement ellipsoids are drawn at the 50% probability level and H atoms are shown as small spheres of arbitrary radii. The dashed line represents the O8—H8B⋯O9 hydrogen bond. |
