Question

which isomerism is not displayed by the following complex?
[Cr(NH3)4(CN)2]Cl

Answer 1

Answer:

Geometrical isomerism is not possible for the complexes with coordination number 2 and 3 and tetrahedral complexes with coordination number 4 because in this case, all the four positions are equivalent. Thus, amongst them, [Ni(CO4)] will not show geometrical isomerism.
