CF And LF Flashcards
Lewis base
Donates e-
Lewis acid
Accepts e-
CO is located at the far
Right of the spectrochemical series
The position of CO in the spectrochemical series is primarily due to the ability of CO to act as a
Pi acceptor
CF
A ligand lone pair is modeled as a point negative charge that repels electrons in the d orbitals of the central metal ion
CF concentrates on
The resulting splitting of the d orbitals into different groups with different energies and uses splitting to rationalize the optical spectra, stability, and magnetic properties of the complexes
Octahedral
18 e- counting
6 point negative charges representing the Ligands are placed around the central metal ion
e on top of t2
Stability of CF metal complex
Stems from attractive interaction between opposite charges of the central metal ion and the point negative charges
Ligand-field splitting parameter
The separation between the two sets of orbitals (delta T and delta O)
The ground state configuration of a complex reflects
The relative values if the ligand-field splitting parameter and the pairing energy
High spin and low spin occur
In the weak-field and strong-field cases
Spectrochemical series
Members are arranged in order of increasing energy of transitions that occur when they are present in a complex
Diamagnetic
Paired e-
Repelled by a magnetic field
Paramagnetic
Unpaired e-
Are attracted by a magnetic field
Tetrahedral
16 e- counting
