Figure 3 A hydrogen-bonded helical chain of the title compound, showing the [R_{2}^{2}](18) and [R_{2}^{2}](8) motifs. For the sake of clarity, H atoms not involved in the motifs have been omitted. For symmetry code (iii), −x + 1, y − [{1\over 2}], −z − [{1\over 2}]. For symmetry code (ii), see Table 1.
