1. Coordination Compoundsby Dr. Atul Kumar SinghAssistant ProfessorDepartment of Chemistry M. L. Arya College, KasbaPurnia -854330India
2. Coordination isomerism This type of isomerism arises due to different placement of ligands in bridged complex. For example
3. Stereo-isomerismThis type of isomerism arises when they contain the same ligands in their coordination spheres but different arrangement in space.
4. Geometrical isomerismThis type of isomerism is also referred as cis- and trans- isomerism. This type of isomerism arises due to ligands occupying different positions around the central metal atom or ion. The ligands occupy positions either adjacent (Cis) or opposite to one another(trans).Geometrical isomerism of compound with coordination number 4 and 6 is common but not possible with coordination number 2 and 3.
5. Geometrical isomerism in complexes with coordination number 4 Complexes with coordination number 4 either have tetrahedral geometry or square planer geometry .
6. Geometrical isomerism in Ma2b2 Complexes
7. Geometrical isomerism in Ma2bc Complexes
8. Geometrical isomerism in Mabcd ComplexesComplexes of the type Mabcd have three isomers
9. Geometrical isomerism in M(ab)2 ComplexesComplexes of the type M(ab)2 containing unsymmetrical bidentate ligands.Complexes of the type Ma3b can not show geometrical isomerism because all spatial arrangements are equivalents.
