Mean bond-length variations in crystals for ions bonded to oxygen

ABSTRACT: Variations in mean bond length are examined in oxide and oxysalt crystals for 55 cation configurations bonded to O2−. Bond-length distortion is confirmed as a statistically significant causal factor of mean bond-length variation. The assignment of a coordination-based radius to O2− is found not to be supported by experimental data. Variations in mean bond length are examined in oxide and oxysalt crystals for 55 cation configurations bonded to O2−. Stepwise multiple regression analysis shows that mean bond length is correlated to bond-length distortion in 42 ion configurations at the 95% confidence level, with a mean coefficient of determination (〈R2〉) of 0.35. Previously published correlations between mean bond length and mean coordination number of the bonded anions are found not to be of
