Calculation of radius ratio for octahedral void in close packed lattice Chemistry Notes
→ Octahedral void is formed by connecting six anions, For understanding it, the transverse section of octahedral void is represented in figure 1.39. Four lattice points are shown to explain this.
→ Here ABC is right angle triangle, in which
r = Radius of void
R = Radius of cube
→ Hence, for getting place in octahedral void in neigbouring close packing lattice, the radius of cation should be 0.414 times of radius of anion.
