WebExamples of Radius Ratio Rule. The ratio of radii of the ions can affect the arrangement of ions in a crystal. Moreover, the limiting ratio has to be greater than 0.414, (radius ratio greater than 0.414) to fit an octahedral arrangement of anions. In this formation, cations will be able to accommodate 6 anions. WebFor eight nearest neighbours (a co-ordination number of 8) the radius ratio r /r must not be less than 0.73. ...
