Figure 3
The molecular structure of (II), showing 50% probability displacement ellipsoids of a section of the infinite chain, O—H⋯I hydrogen bonds and the atom-numbering scheme. Atoms labelled with the additional letters A, B and C are in the symmetry positions (1 − x, 1 − y, 1 − z), (2 − x, 1 − y, 1 − z) and (−1 + x, y, z), respectively. |
