Examples of a complete series of coordination isomers require at least two metal ions and sometimes more. For example, a solution containing ([Co(NH 3) 6] 3+ and [Cr(CN) 6] 3−) is a coordination isomer with a solution containing [Cr(NH 3) 6] 3+ and [Co(CN) 6] 3−.
For example, nitrite can coordinate through O or N. [24] One pair of nitrite linkage isomers have structures (NH 3) 5 CoNO 2+ 2 (nitro isomer) and (NH 3) 5 CoONO 2+ (nitrito isomer). [23] Coordination isomerism occurs when both positive and negative ions of a salt are complex ions and the two isomers differ in the distribution of ligands ...
For example, [Co(NH 3) 6] 3+, which is not octahedral in the mathematical sense due to the orientation of the N−H bonds, is referred to as octahedral. [2] The concept of octahedral coordination geometry was developed by Alfred Werner to explain the stoichiometries and isomerism in coordination compounds. His insight allowed chemists to ...
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.

The second coordination sphere consists of a water of crystallization and sulfate, which interact with the [Fe(H 2 O) 6] 2+ centers. Metal ions can be described as consisting of series of two concentric coordination spheres, the first and second. More distant from the second coordination sphere, the solvent molecules behave more like "bulk ...
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 −
Structural representations used by Alfred Werner (right) and Sophus Mads Jørgensen for one isomer of the dichloride salt of the complex [Pt(NH 3) 2 (pyridine) 2] 2+. [3]Ammine complexes played a major role in the development of coordination chemistry, specifically determination of the stereochemistry and structure.
A coordination polymer is an inorganic or organometallic polymer structure containing metal cation centers linked by ligands. More formally a coordination polymer is a coordination compound with repeating coordination entities extending in 1, 2, or 3 dimensions. [1] [2] It can also be described as a polymer whose repeat units are coordination ...
