A normal spinel compound

An inverse spinel compound

Interstitial compound

Covalent compound

The radius r⁺⁄r⁻ increases as coordination number increases

As the difference in the size of ions increases, coordination number increases

When coordination number is 8, the r⁺⁄r⁻ ratio lies between 0.225 and 0.414

In ionic solid of the type AX(ZnS, Wurtzite), the coordination number of Zn²⁺ and S²⁻ respectively are 4 and 4
