WebMar 15, 2013 · The overall balanced chemical reaction for synthesis of the [Fe(ox) 3] 3-is shown in Scheme 5. It is the sum of three steps, each corresponding to the stepwise reversible binding of ox2-to Fe3+. The metal remains in the labile 3+ oxidation state throughout the reaction, and so by adding a WebDraw a crystal field splitting diagram for [Fe (ox)3]3- and [Cu (ox)2]2-. To complete your diagram, fill in the d-electrons with the hints provided. Hint 1:Both complexes contain weak-field oxalate ligands. Hint 2: [Fe (ox)3]3- has an octahedral geometry and assume [Cu (ox)2]2- has a Jahn-Teller distorted tetragonal geometry. st john\u0027s college bookstore
