Both cis and trans form of the given complex

[M (N H_{3})_{4} C l_{2}]

are optically inactive due to the presence of plane of symmetry and alternate axis of symmetry.

A molecule is said to possess

n

-fold alternate axis of symmetry, if rotation of molecule along the axis by an angle of

360/ n

followed by reflection in a plane perpendicular to the axis results in the same structure.
