Figure 2 . A view of the unit cell content of (I) shown in projection down the b axis. The N–H⋯O hydrogen bonds (blue dashed lines) link molecules into supramolecular chains along the c axis. These are connected into the three-dimensional network by O–H⋯O hydrogen bonds (orange dashed lines), largely obscured in the figure. Colour code: O, red; N, blue; C, grey; and H, green. |
