Figure 2
View of the hydrogen-bonded motif of compound (II ) (Siemens, 1989 ) with the atomic labelling scheme. Displacement ellipsoids are drawn at the 50% probability level and the H atoms are depicted as spheres of arbitrary radii. [Symmetry codes: (i) −x, −y, 1 − z; (ii) −x, y − ½, ½ − z; (iii) x, −½ + y, ½ + z.] |
