Linkage isomers
Linkage isomerism arises when an ambidentate ligand is bonded to the central metal atom/ion through either of its two different donor atoms. e.g. - $\left[ Co \left( NH _3\right)_5 NO _2\right]^{2+}$ Pentaammine nitrito- KN Cobalt (III) ion - N attached $\left[ Co \left( NH _3\right)_5 ONO _2\right]^{2+}$ Pentaammine nitrito- KO Cobalt (III) ion - O attached
