Figure 1
A molecular view of (I) with the atomic numbering scheme. Displacement ellipsoids are drawn at the 50% probability level and H atoms are shown as small spheres of arbitrary radii. Dotted lines represent hydrogen bonds to symmetry-related molecules [symmetry codes: (i) 1 − x, 1 − y, 1 − z; (ii) x, 1 + y, z; (iii) x, y − 1, z]. |
