Coordination isomerism is a form of structural isomerism in which the composition of the coordination complex ion varies. In a coordination isomer the total ratio of ligand to metal remains the same, but the ligands attached to a specific metal ion change.
In coordination chemistry, ligand isomerism is a type of structural isomerism in coordination complexes which arises from the presence of ligands which can adopt different isomeric forms. 1,2-Diaminopropane and 1,3-Diaminopropane are the examples that each feature a different isomer would be ligand isomers.
In chemistry, linkage isomerism or ambidentate isomerism is a form of isomerism in which certain coordination compounds have the same composition but differ in their metal atom's connectivity to a ligand. Typical ligands that give rise to linkage isomers are: cyanide, CN − – isocyanide, NC −; cyanate, OCN − – isocyanate, NCO −
Cisplatin, PtCl 2 (NH 3) 2, is a coordination complex of platinum(II) with two chloride and two ammonia ligands.It is one of the most successful anticancer drugs. A coordination complex is a chemical compound consisting of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands ...
In coordination chemistry, the first coordination sphere refers to the array of molecules and ions (the ligands) directly attached to the central metal atom. The second coordination sphere consists of molecules and ions that attached in various ways to the first coordination sphere.
Aldose-ketose isomerism, also known as Lobry de Bruyn–van Ekenstein transformation, provides an example in saccharide chemistry. [citation needed] An example of an organometallic isomerization is the production of decaphenylferrocene, [(η 5-C 5 Ph 5) 2 Fe] from its linkage isomer.

Sulfoxides can bind to metals by the oxygen atom or by sulfur. This dichotomy is called linkage isomerism. O-bonded sulfoxide ligands are far more common, especially for 1st row metals. S-bonded sulfoxides are only found for soft metal centers, such as Ru(II). Complexes with both O- and S-bonded sulfoxide ligands are known. [4]
Transition metal complexes of thiocyanate describes coordination complexes containing one or more thiocyanate (SCN-) ligands. The topic also includes transition metal complexes of isothiocyanate. These complexes have few applications but played significant role in the development of coordination chemistry. [1]
