Figure 1 A fragment of one-dimensional chain structure of the title compound showing the atom numbering scheme. Displacement ellipsoids are drawn at the 30% probability level. Inter-species hydrogen bonds are shown as dashed lines. For symmetry codes: (i) (−x + 1, −y + 1, −z); (ii) −x, −y + 2, −z). For other codes, see Table 1. |
