What type of hybridization is possible in square planer geometry?
Answers
Answer:
Hybridization is to be used with caution in inorganic chemistry above school level. It is proven not working for one-electron properties at the very least.
0.2) Depending on the details, you may or may not be taught about hypervalent compounds using d-orbitals of outer shell. While this concept fell out of favor, it still is taught here and there.
1) ignoring 0.*, PnX5 family where Pn=P,As,Sb and X is a halogen (typically F or Cl) adopts trigonal-bipiramidal shape and was viewed as an example of sp3d hybridisation. Square planar compounds for p-elements are much rarer, but XeF4 adopt such structure.
2) A rare anion [Ni(CN)5]3− may adopt such structure, specifically in [Cr(NH3)6][Ni(CN)5]⋅2H2O Actually, it is often said that square planar complexes may coordinate weakly an additional ion to form a square pyramid and this is why they are typically much more reactive, than octahedral complexes.
