Solutions to Additional Transition Metal Bonding Problems 1. Cr 3+ has three d-electrons (the 4s electrons are removed before the 3d) so the electron configuration is t 2g 3 . 2. NiCl 4 2- has tetrahedral geometry, while Ni(CN) 4 2- has square planar geometry. The metals with the coordination number of 4 have two possible geometries and in this case the geometry is reflected in the spin. 3. Mn 3+ has four d-electrons. - ligand has a smaller crystal field splitting than does H 2 O, so it should be high spin, just as the H 2 O complex. 4. The paramagnetic complex is high spin. This implies a small value of the crystal field splitting or a low

Unformatted text preview: energy between the t 2g and e g levels. The transition between the two levels will require low energy photons, so orange color light is absorbed and blue light is transmitted. A similar argument occurs for the diamagnetic, low spin complex. The crystal field splitting is large and a more energetic (blue) photon is needed for the transition. Now the orange light is transmitted. Return to: Chem 6 Home Page...
