Figure 3
A view of part of the crystal packing of (I). The figure shows the four hydrogen-bond interactions (thin lines) and the formation of the R33(8) ring. [In the electronic version of the paper, molecules generated by the symmetry codes (i), (ii) and (iii) are represented by the colours green, red and blue, respectively, with hydrogen bonds shown as thin turquoise lines and incomplete hydrogen bonds as thin red lines.] For clarity, only H atoms attached to heteroatoms are shown. (The symmetry codes are as given in Table 1.) |
