Solution
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. - [Co(NH3)5NO2]2+ Pentaammine nitrito-κN Cobalt (III) ion – N attached
[Co(NH3)5ONO2]2+ Pentaammine nitrito-κO Cobalt (III) ion – O attached
