Simple ionic structures are described by two coordination numbers, one for each type of ion. Calcium fluoride (CaF2) is an (8, 4) structure, meaning that each cation Ca2+ is surrounded by eight F− anion neighbors, and each anion F− by four Ca2+.
So coordination number of Ca+2 and F- ion in CaF2 crystal are 8 and 4 resp.
So coordination number of Ca+2 and F- ion in CaF2 crystal are 8 and 4 resp.

Dear Student
The Ca2+and F−are located in CaF2 crystal respectively at face-centred cubic lattice points and in tetrahedral voids.
It is 8:4 arrangement, the coordination number of Ca2+and F−ions is 8 and 4 ions respectively.
I hope this answer will help you.
Thanks & Regards
