Figure 1
A molecular diagram for (I), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 40% probability level and H atoms have been omitted, apart from those involved in hydrogen bonds, which are shown as small spheres of arbitrary radii. Full ellipsoids denote the independent molecule and open ones the symmetry-related moiety at (1-x, 1-y, 1-z), and double broken lines denote the π–π intaraction linking them. Single dashed lines denote the hydrogen bonds. |
