Figure 2
Part of the crystal structure of (I) , showing the formation of a C22(17) chain of type A molecules along [010], 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, −z), (2 − x, + y, − z), ( − x, 1 − y, + z) and (x, 1 + y, z), respectively. |
