各元素の、結晶半径 (Crysatal radius) およびイオン半径 (Ionic radius) の一覧を掲載します。このデータは Shannon, R. D., Acta Crystallogr. A32, 751, 1976. の引用です。細かい表記の意味は原著論文を参考にしてください。
SQ: Square planar coordination
PY: Pyramidal coordination
R: From r3 vs. V plots
C: Calculated from bond length-bond strength equations.
E: Estimated from one or more plots of r vs. valence, r vs. CN, and r vs. cell volume.
?: Doubtful
*: Most reliable
A: Ahrens (1952) ionic radius
P: Pauling’s (1960) crystal radius
M: From a compound having metallic conductivity.
なお、Shannonのイオン半径はすべての価数や配位数に対して与えられているわけではありません。最近では、機械学習によるイオン半径の推定も行われています。興味のある方はこちらをご覧ください。
