Chapter 20
 Hybridization schemes for σ-bonding frameworks and various geometries
 Limitations of valence bond theory
 High-spin and low-spin configuration
 Absorption, emission and notation to indicate
 Crystal Field Theory
 Δo, Δt
o splitting of degeneracy of orbitals relative to barycenter
o trends in magnitude
 Crystal field stabilization energy (CFSE),
o how to calculate for different geometries, w/ P (pairing energy)
o Four factors affecting the CFSE
 Weak-field ligand, strong field ligand and influence on spin state
 spectrochemical series
 pairing energy
 Be able to predict of a complex is high/low spin, corresponding electron configuration (e.g
t2gxegy or ext2y)
 Derivation of distorted octahedral, square planar, orbital energy levels
 Jahn-Teller distortions, reasons behind and which e- configurations tend to exhibit.
 Given splitting of orbitals for non-octahedral, tetrahedral, square planar type, be and to
complete diagram and estimate spin, etc.
 Be able to sketch ligand to metal σ-bonding, note which types of ligands exhibit
 MO diagram for ML6 with σ-bonding only, be able to derive symmetries of orbitals on both
metal and ligand set given character table for particular geometry/point group. Note
interactions of same symmetry type to form bonding/antibonding MOs.
 18-electron rule
 -donor ligand, -acceptor ligand, sketch bonding/antibonding interactions, role of these
to explain anomalies in spectrochemical series.
o metal to ligand
o ligand to metal
o pi-acceptor, pi-donor ligands
 d-d transitions
 quantum numbers for multielectron species
 term symbols, L,S,J, spin multiplicity

term symbols

o Ordering of terms by energy
o Rules for more and less than half-filled
 Complexes and color, be able to predict color of complex given spectrum/absorption
color for simple absorption.
 Understand relationships between ligands, Δo, energy, color
 Charge transfer absorption, what type of compound is likely to exhibit.
o MLCT
o LMCT
