CALCULATION Calculate Etet-Eoct>0. If positive, the oct complex is favored. If 1.27deltaO>Pic+Pie Delta E=E(lo)-E(hi) If Delta E=-DeltaO+Pic Lo spin is favored if delta E is negative so: Delta>Hc ORBITALS The better the Orbital overlap the d orbitals have with the ligand sigma group orbitals, the greater their energy will be. When drawing orbital diagrams for the metal side, put M, then d, then s, and then p at the top. 4s is greater than d because 4s shielded by 3d, and not vice versa. The dxy orbital can interact with 4 pi* orbitals, while dxz and dyz can interact with only 2. Hence, the dxy orbital experiences more interaction and stabilization through Pi-backbonding. (With a Pi acceptor ligand like CO) COLOR Ni(NH3)6 to Ni(H2O)6: Orange light is absorbed, so a blue color is shown. Then red light is absorbed, and green color is observed. This is because H2O is a weaker base than NH3. Stronger, base=stronger field ligand=larger deltaO= greater energy of light absorbed. ELECTRON DIAGRAMS FOR LIGANDS W/ METAL eg* stays the same energy Pi acceptor ligands M->L: Sigma bonds only t2g interacts with empty ligand group orbital t2g to form t2g and probably empty t2g * (very high in energy)largest Delta O. Pi donor ligands L->M: Sigma bonds only t2g interacts with filled logan group orbital to form most stable t2g and slightly unstable t2g*smallest delta O. Made with nCreator - tiplanet.org
