Name Of Ligands In Coordination Compounds 4w4828

c Atoms or group of atoms (in the form of ion or neutral molecules or ions) associated with central atom by forming co-ordinate bond in a co-ordination complex are called .

Anionic ligands have names ending in 'o'. The last "e" in names of negative ions are changed to "o". [ "-ide" -ido (e.g. chloride chlorido), "-ate" -ato (e.g. sulfate -sulfato,), and "ite" -ito (e.g. nirite nitrito) Anion came
