Solution: Coordination numbers depend on stoichiometry. The sizes of the ions have been reduced to show the coordination environments clearly.How many anions per unit cell for ScF3?

Problem

Sodium fluoride has the cation coordination number 6, with octahedral geometry and the anion coordination number is also 6 with octahedral geometry. Magnesium difluoride has the cation coordination number 6, with octahedral geometry and the anion coordination number is 3 with trigonal planar geometry. Scandium trifluoride has the cation coordination number 6, with octahedral geometry and the anion coordination number is 2 with linear geometry.
