Figure 4
Part of the crystal structure of (I), showing the formation of a centrosymmetric hydrogen-bonded R22(20) ring which links pairs of (100) sheets. Dashed lines indicate hydrogen bonds. For the sake of clarity, H atoms not involved in the motif shown have been omitted. Atoms marked with an asterisk (*) are at the symmetry position (−x + 1, −y, −z + 1). |
