Table 2. Statistical significance (σ levels) and electron-density values (e Å−3, shown in parentheses) of omit-map features at the O1–O6 and O6* sites in Li et al. (2024 ▸).
Values are obtained from independent polder omit maps. A dash (—) indicates that electron density is not detectable at the corresponding site.
