Figure 2
A view of the chain parallel to the c axis formed by the action of one N—H⋯O hydrogen bond augmented by two C—H⋯O hydrogen bonds, all involving atom O4 as the acceptor. Atoms labelled with an asterisk (*) or a hash (#) are at the symmetry positions (1 − x, 1 − y, − + z) and (1 − x, 1 − y, − z), respectively. H atoms not involved in the hydrogen bonding have been omitted for the sake of clarity. |
