COMPLEXES
Compounds, which are formed by a
combination of two or more simple atoms and
can be found independently in the solution
are called COMPLEX compounds.
COMPLEXES
The complex formation occurs from a ligand (L) around a central atom (M). Ligands are
covalently bonded to the central atom. The number of ligands ranges from 2 to 8. It is usually 4-6. Ligands can be neutral or
charged groups.
If only one ligand is attached to the central atom, if the unidentate is bound to the two ligand center atoms, then the bidentate is connected to the three ligand center atoms.
If the terdentate is connected to the four ligand center atoms, this is quadridentate. ... and so on.
