Interpretation:
The possible isomers for square planar isomer
Concept Introduction:
Isomers:
The compounds with same molecular formula but differ in the arrangement of the atom are said to be isomers.
Linkage isomers:
Linkage isomerism occurs with ambidentate ligands that are capable of coordinating in more than one way.
Example:
Hydrate Isomers:
Hydrate isomers results from replacement of a coordinated group by a solvent molecule in this case it is a water molecule.
Coordination Isomers:
Coordination isomerism arises in compounds containing complex anionic and cationic parts. Hence, there are two complex compounds bound together, one with a negative charge and the other with a positive charge. In coordination isomers, the anion and cation complexes of a coordination compound exchange one or more ligands.
Ionization Isomers:
Ionization isomers occur when a ligand is bound to the metal center exchanges places with an anion or neutral molecule that was previously outside the coordination complex.
Geometrical isomers:
If there is restricted rotation in a molecule there arises geometric isomerism. Geometric isomers are also known as Cis- trans isomerism.
- If the two atoms locked in same side of the molecule then it is called as cis isomers.
- If the two atoms locked in opposite side of the molecule then it is called as trans isomers.
