Figure 2 A fragment of the molecular packing. H-atoms have been omitted for clarity with exception to those participating in weak interactions. The red dashed lines denote the H-bonds, the green dashed lines denote the π⋯π interactions and the black dotted lines denote the C—H⋯π contacts. Cg1, Cg2,Cg3 and Cg4 are respective centers of gravity of C10–C15; C30–C35; C1,N1,C2,N2,C3,C4 and C21,N21,C22,N22,C23,C24 rings. Symmetry codes: i) −x + 1, −y + 1, −z + 2; ii) x, y, z + 1; iii) −x + 2, −y + 1, −z + 2. |
