Question

Which one of the following has a square planar geometry?

• A. $[FeC{l}_4{]}^{2-}$
• B. $[NiC{l}_4{]}^{2-}$
• C. $[PtC{l}_4{]}^{2-}$
• D. $[CoC{l}_4{]}^{2-}$

Answer 1

The correct option is C $[PtC{l}_4{]}^{2-}$

$[PtC{l}_4{]}^{2-}$ is a square planar complex. All the complexes of Pd (II) ad Pt (II) are square planar.
