Figure 1
View of the hydrogen-bonded motif of compound (I ) (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 − ½, ½ − y, 1 − z; (ii) ½ + x, ½ − y, 1 − z; (iii) 1 + x, y, z.] |
