Figure 7
Part of the crystal structure of compound (II), showing the formation of a C(4)C(4)[R22(7)] chain of rings along [010] built from C—H⋯N and C—H⋯O hydrogen bonds. For the sake of clarity, H atoms bonded to C atoms which are not involved in the motif shown have been omitted. Atoms marked with an asterisk (*) or a hash (#) are at the symmetry positions (x, y − 1, z) and (x, y + 1, z) respectively. |
