Figure 4 View of the partial unit-cell contents in projection down the b axis with the tree-dimensional hydrogen bonding network. Dashed lines represent the N—H⋯O, O—H⋯O and C—H⋯O hydrogen bonds. Hydrogen atoms not involved in hydrogen bonding have been omitted for clarity. [Symmetry codes: (ii) −x, −y + 1, −z + 1; (iii) −x + 1, −y + 1, z + 1; (vi) x, y, z − 1.] |
