Notes

The "effective ionic radii" quoted here assume that the ionic radius of F- is 133 pm and that of O2- is 140 pm.

Values depend upon the coordination number and for d-block metals whether or not the metal is in a high or low spin state.

Older "crystal ionic radii" are based upon a radius of six-coordinate F- = 119 pm and are 14-18% larger than effective ionic radii.
