(a) Stereoisomerism
(i) Geometrical isomerism
(ii) Optical isomerism
(b) Structural isomerism
(i) Linkage isomerism
(ii) Coordination isomerism
(iii) Ionisation isomerism
(iv) Solvate isomerism
Stereoisomers have the same chemical formula and chemical
bonds but they have different spatial arrangement Structural isomers
have different bonds A detailed account of these isomers are
given below This type of isomerism arises in heteroleptic
complexes due to different possible geometric
arrangements of the ligands
