Coordination Chemistry 5: The Angular Overlap Method and d-Orbital Splitting Diagrams
Channel: Oxford College Chemistry Courses: Scharf
Date: 2023-05-15

This video illustrates the principles of the "Angular Overlap Method" of generating d-orbital splitting diagrams for transition metal complexes, and how those diagrams are populated with electrons. We illustrate this process for octahedral, square planar, and tetrahedral geometries.

(Expert Notes: This is a σ-only treatment; π- and δ-contributions are not covered in this course. Further, this is a qualitative approach, so we do not derive or utilize the angular overlap parameter eσ. Additionally, we do not use the classical d-orbital splitting diagram for square planar geometries from crystal field theory; we prefer the approach utilized by Ritter, et al. in J. Chem. Ed. 2016, 93, 118.)
