The intermolecular interactions in (I), including the three-center hydrogen-bond configuration. For clarity, only relevant H atoms and intramolecular interactions are shown. Atoms marked with symbols are at the following positions: ($) x + 1, y, z; (#) −x + 2, −y + 1, −z + 1; (*) −x + 1, −y + 1, −z + 1; ($$) −x + 2, −y, −z + 1; (##) −x + 2, −y + 1, −z; (**) x − 1, y + 1, z. |
