Order the extinction coefficients of the following three manganese complexes according to their magnitude. Consider only d-d transitions, and explain your answers. Note: Consider the type of ligands (weak-field vs. strong-field) when deciding whether the complexes are high-spin or low-spin. [Mn(H2O)6]2+, [MnCl4]- , and [Mn(CN)6]4- .

We discussed in class how ligands can affect the A. energy splitting. a. Categorize these complexes by whether their ligands are mainly i acceptors, i donors, or o donors. [Cr(CN)6]4-, [Fe(H20)6]2+, [CO(NH3)6]2+, [Cu(H20).]2+ b. Draw the tag-eg splitting and show the electron count for each complex from part a. Categorize each as high or low spin or write neither if both electron filling methods give the same result. Assume all o and i donors given here are weak-field ligands.
