Figure 1
The molecular structures of bix·2H2O in polymorphs (I) and (II), showing the atom-numbering schemes. Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. Hydrogen bonds are shown as dashed lines. In polymorph (II), atoms labeled with the suffixes A and B are at the symmetry positions (−x + 1, −y + 1, −z) and (−x + 3, y, −z + ), respectively. The minor components of the disordered water molecules have been omitted for clarity. In (I), atoms labeled with the suffix C are at the symmetry position (−x, −y + 2, −z + 1). |
