Figure 3 Packing diagram showing the molecular arrangement in the unit cell. Non-classic hydrogen bond interactions are represented with red dashed lines, meanwhile other weak non-covalent contacts are represented with orange and green dashed lines. Most of the hydrogen atoms were omitted for clarity. Symmetry codes: (i) –x + , y + , –z + ; (ii) x + , –y + , z–1/2; (iii) –x + 1, –y + 1, –z + 1; (iv) x, y + 1, z–1. |
