Figure 2 The C—H(methyl)⋯π and C—H(methylene)⋯π interactions between the mononuclear units, forming a layer in the bc plane. The Cg1 and Cg2 are the centroids of the C9—C10—C11—C12—C13—C14 and C2—C3—C4—C5—C6—C7 rings, respectively. Symmetry codes: (i) x, −y + 2, z − ; (ii) x, y + 1, z; (iii) x, −y + 2, z + . |
