Figure 3
A packing diagram (with unit cell) of the hydrogen-bonding and contact geometry in the zigzag chain along (010) in (Ia). Only two H atoms, H11A and H22, involved in these interactions and contacts have been included for clarity. [Symmetry codes: (i) 1 − x, y + , −z + ; (ii) x, 1 + y, z; (iii) 1 − x, y − , −z + .] |
