Figure 2
Detail of a (011) hydrogen-bonded sheet in (I[link]) with the selenite groups represented by HSeO3E pseudo-tetrahedra (dummy atom E placed 1.0 Å from Se). Colour key: [HSeO3E]− groups pink, O atoms red, C atoms blue, N atoms green, H atoms grey, E dummy atoms light blue (all radii arbitrary). The H⋯O portion of the intramolecular hydrogen bond is highlighted in light blue. The H⋯O portions of the N—H⋯O hydrogen bonds with 1.90 Å < d(H⋯O) < 2.30 Å and 2.30 Å < d(H⋯O) < 2.55 Å are highlighted in yellow and orange, respectively. Symmetry labels as in Table 2[link].
