(a) Variation in calculated bonded radii for second- (red), third- (green) and fourth- (yellow) row cations bonded to O2− as a function of experimental 〈M–O〉 bond lengths; (b) variation in calculated bonded radii for O2− bonded to second- (red), third- (green) and fourth- (yellow) row cations; data for silicate and oxide structures (modified from Gibbs et al., 2013). |
