We’re being asked to determine the anion coordination number in MgF2. A coordination number represents how many nearest neighbors at atom has in the extended crystal lattice. Since the unit cell makes up the crystal lattice, coordination number is how many other atoms are in contact with that one atom.[readmore]For this problem, we will first determine the crystal lattice of MgF2 then the coordination number of the anion.MgF2 resembles a rutile crystal where the coordination number of its cation is 6 and the coordination number of its anion is 3. The structure of the crystal is shown below. Rutile forms tetragonal crystals. The coordination number of its cation (gray) is 6. The coordination number of its anion (red) is 3.For rutile crystal lattice:C.N. of cation = 6C.N. of anion = 3For MgF2, the cation is Mg2+ and the anion is F-.We are given: C.N of Mg2+ = 6Since F- is the anion, C.N. of F- = 3. The anion coordination number in MgF2 is 3.
