Figure 6
Part of the crystal structure of (III), showing the formation of a centrosymmetric dimer by means of symmetry-related C—H⋯π(arene) hydrogen bonds. For the sake of clarity, H atoms bonded to C atoms which are not involved in the motif shown have been omitted. The atom marked with an asterisk (*) is at the symmetry position (1 − x, 1 − y, 1 − z). |
