Two principal types of isomerism are known among
coordination compounds Each of which can be further subdivided (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
