All of the above

Vedclass · Answer

(D) The complex $[CO(NO_2)(SCN)(en)_2]Br$ exhibits the following types of isomerism: $1$. Geometrical isomerism: Due to the presence of two $(en)$ ligands and two different monodentate ligands $(NO_2^-, SCN^-)$,it can exist in $cis$ and $trans$ forms. $2$. Linkage isomerism: The ligands $NO_2^-$ (nitro/nitrito-$N$) and $SCN^-$ (thiocyanato-$S$/isothiocyanato-$N$) are ambidentate ligands,which can coordinate through different donor atoms. $3$. Ionization isomerism: The $Br^-$ ion is outside the coordination sphere and can exchange with the ligands inside the sphere (e.g.,$NO_2^-$ or $SCN^-$). Therefore,the complex exhibits all of the above types of isomerism.

The coordination compound with the molecular formula $[CO(NO_2)(SCN)(en)_2]Br$ exhibits which of the following types of isomerism?
