(a) Crystal packing of compound I, viewed in a projection nearly on the ab plane, showing a non-covalent layer assembled by π–π and C—H⋯O interactions (identified by dotted lines). (b) Packing of two successive corrugated layers. [Symmetry codes: (i) x + 1, y, z; (iii) −x + 1, −y + 1, −z + 1; (iv) −x + 1, −y + 2, −z + 1.] |
