Q. Show diffrent type of Ligands?
Ligands which contain one donor atom are called monodentate the donor atom may contain
One or more than one lone pairs of electrons. The ligands that contain two, three, four and so on donor atoms are called bidentate, tridentate. tetradentate etc., respectively. For example, .NH3, H20, F- are all monodentate ligands: CO2-3, SO2-4, H2NCH2COOH (glycine) are all bidentate ligands. Table 14.1 gives a list of anions/molecules commonly used as ligands.
A bidentate ligand like ethylenediamine is a neutral molecule but a glycinate ion, H2NCH2COO-, which is not neutral can also act as a bidentate ligand. The nitrogen atom and one of the oxygen atoms of glycinate ion can form chemical bonds with a metal ion. In order to differentiate a ligand like glycinate we call it a bidentatemo no negative ligand.
