It is a wholesome project for distinguishing the branches of Transition Metal Complex along with its structural formula and its structures. Overall its a conceptual power point for the followers in engineering stream of their 1st year.

2. Introduction
Isomerism: Two or more compounds that have the same chemical
formula but a different arrangement of atoms are called isomers and
the phenomenon is called isomerism. Because of the different
arrangements of atoms, they differ in one or more physical or chemical
properties. Isomers are of two types:
Structural isomerism: Same formula different connectivity.
Stereoisomerism: Same formula same connectivity.

3. Structural Isomers
Here ligands interchange between cationic and anionic
entities of different metal ions present in a complex.
Coordination compounds having same composition but differ in
connectivity of the ligand to the metal.
The counter ion in a complex salt is itself a potential ligand and
can displace a ligand which can then become the counter ion.
Linkage Isomerism Coordination Isomerism
Ionisation Isomerism Solvate Isomerism
The compounds which differ depending on the number of the
solvent molecule directly bonded to the metal ion.

4. Geometrical Isomerism
This type of isomerism occurs in heteroleptic complexes with
coordination numbers 4 to 6. It arises due to the difference in the
geometrical arrangement in the ligands around the central metal ion.
When same ligands occupy the adjacent position in the polyhedral, it is
known as cis-isomer whereas when the same ligands occupy the
opposite position in the polyhedral is known as trans-isomer.

6. Octahedral Complexes

7. Optical Isomerism
The compounds which do not have a plane of symmetry show optical
isomerism. The optically active isomers have non-superimposable mirror
images on which cannot be superimposed on one another and these molecules
are called chiral.
The two forms called dextro(d) or laevo(l) depending upon the direction they
rotate the plane of polarized light in a polarimeter are called. enantiomers.
An equimolar mixture of dextro and laevo rotatory isomers is called racemic
mixture. Optical isomerism is commonly shown by the octahedral isomers
involving didentate ligands
