A CN=8 Cubic coordination B CN=4 Tetrahedral coordination
AB2 type crystal structure (CaF2): Blue – Ca Yellow- F
Co ordination number of A(For example Ca)= 8 (White one is surrounded by 8 neighbours) Co ordination number of B(For example F)= 4 (yellow one is surrounded by 4 neighbours) Hope you understood.
