Then you look at Q. M, which is the overall charge of the complex, plus the number of X type Liggins, plus two times the L type Liggins. Remember these components, and you'll always be able to calculate the electron count for any transition metal complex.

WebBoth complexes have the same metal in the same oxidation state, Fe 3+, which is d 5. Water is a weak field ligand (high spin) so the electron configuration is t 2g 3 e g 2 with LFSE = 0. Cyanide is a strong field ligand (low spin) so the electron configuration is t 2g 5 with LFSE = –20Dq + 2P.
