(a) Hydrogen bonds [symmetry codes: (i) x, y + 1, z; (ii) −x − 1, −y + 1, −z; (iii) −x − 1, −y + 1, −z + 1] (blue dashed lines), π-stacking interactions (symmetry operation: −1 − x, 1 − y, 1 − z) and Y—X⋯Cg (symmetry operation: x, −1 + y, z) (red dashed lines) in the unit cell of compound (I). (b) A view of the ring motifs along the c axis with the strongest hydrogen bonds and π-stacking interactions indicated by red dotted lines. |
