Figure 1
A perspective view of the molecule of (I), showing the atomic numbering scheme for the asymmetric unit. 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, which are drawn with dashed bonds and empty ellipsoids. Primes and double primes indicate molecules at symmetry positions (1 − x, 2 − y, 1 − z) and (2 − x, 2 − y, 1 − z), respectively. |
