ligand和transition metal 的联系 以及两者之间对不同co-ordinate number的影响

ligand and transition metal co-ordinates together to make transition metal complex

The number of co-ordinate number depends on the type of ligand:
1. H2O NH3 usually form octahedral complex
2. Cl- OH- usually form tetrahedral complex
3. Ag+ (acts as the central metal ion) usually form linear complex

ligand is a lone pair of electron donor
transition metals are those which have incomplete d or f shells in either its element or ion form

p.s. Zn or Zn2+ ARE NOT TM!
