Figure 5
[001] projection of the unit cell and detail of the hydrogen bond between GII and GIII of HTGS at 298 K with hydrogen bonds shown as dashed lines. The short O15—H15⋯O3 bonds are shown as pink dashed lines. Atoms N11 and N11B are disordered with occupancies of 87.5%/12.5%. Model 1 (a); a single-minimum potential energy model for H5; model 2 (b); a double-minimum potential-energy model for H15 and H3. Symmetry codes: (v) 1 − x, − + y, 1 − z; (vi) 1 − x, − + y, 2 − z; (vii) x, −1 + y, 1 + z. |
