linkage isomerism

Such compounds give rise to linkage isomerism.

Linkage isomerism occurs with ambidentate ligands that can bind in more than one place.

Linkage isomerism is the existence of coordination compounds that have the same composition differing with the connectivity of the metal to a ligand.

These complexes illustrate linkage isomerism for the ligand DMSO.

Linkage isomerism is only one of several types of structural isomerism in coordination complexes (as well as other classes of chemical compounds).

Key words: selenite, thiosulfate, selenopentathionate, Se-77 NMR, Raman spectroscopy, linkage isomerism.

The first reported example of linkage isomerism had the formula [Co(NH)(NO)]Cl.

There are four types of structural isomerism: ionisation isomerism, solvate or hydrate isomerism, linkage isomerism and coordination isomerism.

The proper notation for linkage isomerism is the kappa notation where the atom directly bonding to the metal is proceeded by the lowercase Greek letter kappa; κ.

•H2O during dehydration to anhydrous LiNO2 are interpreted as evidence for an ordered distribution of NO2− ions over two non-equivalent sites (akin to linkage isomerism) in anhydrous LiNO2.
