E12 Calculation of Limiting Radius Ratios

Using Pythagoras’ theorem, the length of the side and the body diagonal of a cube are related: d 2 = a 2 + a 2 + a 2 = 3a 2 = 3 × 4r-2 = 12r-2 d = 2(3) 1/2 r- So, 2r-+ 2r + = 2r(3) 1/2 r- r + / r-= (3) 1/2 – 1 = 0732 As long as the radius of the cation is no smaller than 73% that of the anion, the CsCl structure, with its high Madelung constant, is possible If the cation is larger than ,
