Part of the crystal structure of (I), showing the formation of a chain of edge-fused R44(40) rings. Hydrogen bonds are indicated by dashed lines. For the sake of clarity, H atoms not involved in the motif shown have been omitted. [Symmetry codes: (iii) x, y, z − 1; (vi) −x, y − , −z; (vii) x, y, z + 1; (viii) −x, y + , −z.] |
