Figure 1 The molecular structure showing displacement ellipsoids drawn at the 30% probability level. The light broken lines depict O—H⋯O hydrogen bonds. The propane-1,2-diol molecule and the sulfate ligand are disordered over two symmetry-related positions but the disorder is not shown. Unlabeled atoms are related to the labeled atoms by the symmetry operator (−x, y, −z + ). |
