Ch 24 + 10-11 VB+MO Desc, Coordinization Comples, Nuclear Rxns Flashcards
2(non stationary lone pairs + pi bonds)
Pi electrons
Lewis acids
Accepts electron pairs (transition metals and boron column)
Lewis bases
Donates Electron pairs called Ligands (p block elements usually have lone pairs)
Coordination number
Number of bonds Ligands form
Bidentate Ligands
Oxalate =2 bonds formed and 2- charge
En =2 bonds formed and no charge
Carbanato= CO3 forms 2 bonds 2- charge
Naming coordination complexes 1. 2. 3. 4. 5.
- Link Ligands and metals together. Ligands alphabetically. Metal last (include oxi # at end for metal)
- Ionic compounds with complexes is cation (space) anion
- Anionic Ligands- end with o
- Use Greek prefixes di,Tri, tetra etc. or bis,tris, tetrakis for Ligands that have prefixes in the name
- Anionic metal complexes- add ate to latin word for metal
