Figure 4
Part of the crystal structure of (II), showing the formation of a hydrogen-bonded chain along the (−, y, ) direction. For the sake of clarity, H atoms not involved in the motif shown have been omitted. Selected atoms are labelled. Dashed lines indicate hydrogen bonds. Cg is the centroid of the C11–C16 ring. [Symmetry codes: (i) −x, −y, 1 − z; (ii) − + x, − y, + z.] |
