1. For CaF2, calculate the lattice energy using the Born-Landé equation, the Born-Mayer equation (using d* = 34.5 pm), the Kapustinskii equation, and using a Born-Haber cycle. Cite your source for each datum used in these calculations.
2. For each of the following transition metal complexes, find the LFSE in units of Dq, indicate if the complex is Jahn-Teller active, and give the point group of the complex.
a. [Fe(CN)6]4–
b. [Co(CN)6]3–
c. [Ni(CN)6]4–
