^aSee table footnote of Table 3 for the description of the fit parameters. r̅_LiO is the weighted mean of the two fitted Li–O distances. Fixed values are indicated by an asterisk, and bound values are indicated by a dagger (see text for details). The valence, v_LiO, for each Li–O peak is calculated using bond valence parameters.^85,87 Statistical errors from the fits are given in parentheses.
