4
Q
ionic type L ligand
A
Consider as 2 electron donors
5
Q
X2 ligand
A
Divalent species with 2 unpaired electrons, forms double bond with metal centre
6
Q
Denticity
A
Number of donor atoms that bond to metal centre
7
Q
Bridging ligands
A
Type X ligands sometimes have extra lone pair that can form another co-ordinate bond
8
Q
Ambidentate
A
More than one donor atom but ligand only co-ordinates through one donor atom at a time
9
Q

A
Halide donors and oxygen donors are weak
Nitrogen donors and carbon donors are strong
