Why is geometrical isomersim not possible for tetrahedral complexes?

Square planar complexes of MX_(2)L_(2) type with coordination number of 4 exhibit geometrical isomerism whereas tetrahedral complexes with similar composition do not. Why? Justify the formation of a low spin complex and a high spin complex taking the examples of [Fe(CN)_(6)]^(3-) and [FeF_(6)]^(3-) on the bases of "crystal field splitting energy". (Delta_(0))

how many geometrical and optical isomers are possible for the complex ion, [ Cocl_(2)(en)_(2)]^+ ?

Geometrical isomerism is not shown by:

Why is optical isomerism not shown by square planar complexes?
