Figure 3
Part of the crystal structure of (I) , showing the formation of a C22(16) chain of type B molecules along [001], built from the alternating action of two C—H⋯O hydrogen bonds. For the sake of clarity, H atoms not involved in the motif shown have been omitted. Atoms marked with an asterisk (*), a hash (#), a dollar sign ($) or an ampersand (&) are at the symmetry positions ( + x, − y, 1 − z), ( − x, 1 − y, + z), (1 − x, + y, − z) and (x, y, 1 + z), respectively. |
