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 ...
Six isomers of bipyridine exist, but two are prominent. 2,2′-bipyridine , also known as bipyridyl, dipyridyl, and dipyridine, is a popular ligand in coordination chemistry [ 2 ] [ 3 ] 2,2′-Bipyridine
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 ...
trans-Dichlorodiammineplatinum(II) is the trans isomer of the coordination complex with the formula trans-PtCl 2 (NH 3) 2, sometimes called transplatin. [1] It is a yellow solid with low solubility in water but good solubility in DMF. The existence of two isomers of PtCl 2 (NH 3) 2 led Alfred Werner to propose square planar molecular geometry. [2]
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.

There are four triazole isomers, which are conventionally divided into two pairs of tautomers. In the 1,2,3-triazoles, the three nitrogen atoms are adjacent; in the 1,2,4-triazoles, an interstitial carbon separates out one nitrogen atom. Each category has two tautomers that differ by which nitrogen has a hydrogen bonded to it.
In one isomer the CO ligands are terminal. When a pair of CO are bridging, cis and trans isomers are possible depending on the location of the C 5 H 5 groups. [7] Another example in organometallic chemistry is the linkage isomerization of decaphenylferrocene, [(η 5-C 5 Ph 5) 2 Fe]. [8] [9] Formation of decaphenylferrocene from its linkage isomer
