Figure 5
A partial packing diagram for (I), viewed along the a axis, showing the formation of R22(6), R22(9) and R44(18) ring motifs. N—H⋯N, N—H⋯O and C—H⋯O interactions are shown as dashed lines. Intermolecular C3—H3B⋯O6iii contacts and H atoms not involved in interactions have been omitted for clarity. Selected atoms of the molecules present in the asymmetric unit are labelled, primarily to provide a key for the coding of the atoms. [Symmetry codes: (i) −x + 2, −y, −z + 1; (ii) −x + 1, −y, −z; (iii) x − 1, y, z; (iv) x + , −y + , z + .] |
