Figure 1
View of the molecular structure of I showing atom-labelling scheme with displacement ellipsoids drawn at the 30% probability level. C-bound H atoms are omitted for clarity. Hydrogen-bonding interactions are shown as dotted lines. [Symmetry codes: (i) −x + 2, −y + 1, −z + 1; (ii) −x + 1, −y + 1, −z); (iii) x − 1, y, z − 1]. |
