\left[Pt{\left({NH}_{3}\right)}_{2}{Cl}_{2}\right]is a square planar complex and $it can exhibit geometrical isomerism. It has two isomers, cis-platin and trans-platin. The complexes$\left[Zn{$\left({NH}_{3}\right)$}_{2}{Cl}_{2}\right]\left(tetrahedral\right)$and$\left[Pt ( en ) ( SCN{)}_{2}\right]$does not exhibit geometrical isomerism. The octahedral complex$\left[Pt{$\left({NH}_{3}\right)$}_{2}{Cl}_{4}\right]$shows geometrical isomerism, it has two geometrical isomers cis and trans.</p><p>${\left[Cr ( en{)}_{2}$\left({H}_{2}O\right)\left({SO}_{4}\right)$\right]}^{+} is an octahedral complex, it is of the type $M{\left(AA\right)}$_{2}bc$and it can exhibit the geometrical isomerism.</p>$
