Figure 5
A partial packing diagram of compound (II), showing a double-chain structure formed by O—H⋯N/N—H⋯O hydrogen bonds, C—H⋯O interactions (black dashed lines) and π–π stacking interactions (brown dashed lines). H atoms not involved in the above interactions have been omitted. [Symmetry codes: (ii) x − 1, y, z + 1; (v) −x + 1, −y + 1, −z + 1: (vi) −x + 2, −y + 1, −z.] |
