Figure 2
Part of the crystal structure of (I), showing the intermolecular O—H⋯N (m) and N—H⋯O (n) hydrogen bonds (dashed lines) running vertically, which can be described by the graph-set notation C(7) and together produce a sheet parallel to the (001) plane and built up from the R44(18) rings. All aromatic H atoms have been omitted for clarity. [Symmetry codes: (i) 2 − x, + y, − z; (ii) 1 − x, − + y.] |
