Figure 2 A partial view of the crystal packing of the title compound. Both the hydrogen bonding [symmetry codes: (i) x-1, y, z; (ii) x, −y+1/2, z+1/2; (iii) x+1, y, z+1] and π⋯π interactions [symmetry codes: (ii) x, −y+1/2, z+1/2; (iv) −x+1, y+1/2, −z+1/2] are shown as dashed lines; ring centroids are marked by small spheres. See Tables 1 and 2 for details. |
