Figure 3
The molecular structure of a pair of (IIIa) molecules. The upper molecule is generated by inversion [symmetry code: (i) −x, 2 − y, 1 − z]. Intermolecular Se⋯Se and Se⋯H contacts and O—H⋯O hydrogen-bond bridges are indicated by dashed lines. The outwardly directed hydrogen-bond bridges produce a chain of pairs. Displacement ellipsoids are drawn at the 50% probability level. Only selected H atoms are displayed.
