Transition Metal Chemistry Flashcards
1
Q
High/Low Spin
A
High Spin:
- weak ligand
- small ∆o
- follows Hund’s rule
Low Spin:
- strong ligand
- large ∆o
- fills lower energy orbitals first
2
Q
Linkage Isomerism
A
coordination compounds that have the same composition differing with the connectivity of the metal to a ligand
3
Q
Coordination Isomerism
A
composition of the complex ion varies
4
Q
Geometric Isomerism
A
stereoisomerism - cis or trans
5
Q
Ionisation Isomerism
A
ligand exchanges places with anion
6
Q
Optical Isomerism
A
differ three-dimensionally by the placement of substituents around one or more atoms in a molecule.
7
Q
Ligand Strength
A
more electronegative = less likely to donate electrons = weaker ligand field
8
Q
phen
A
- 3 benzene rings (outer 2 contain N)
- uncharged
- strong ligand
- bidentate
9
Q
en
A
- ethylenediamine
- uncharged
- weak ligand
- bidentate
10
Q
edta
A
- binds to four O’s and two N’s
- charge of -4
- hexadentate
11
Q
ox
A
- two carbons each w/ one =O and one -O
- charge of 2-
- strong ligand
- bidentate
