Figure 2 Graphical representation of a part of one two-dimensional layer formed by 1 in the solid state due to formation of intermolecular hydrogen bonds along the crystallographic b- and c-axes. All C-bonded hydrogen atoms are omitted for clarity. Symmetry codes: (A) −3/2 – x, + y, 1/2 – z. (B) − + x, 1/2 – y, − + z. (C) −1 – x, – y, 1 – z. (D) − + x, 1/2 – y, + z. (E) −1/2 – x, + y, 3/2 – z. |
