Why is PtCl4^2- square planar? | Socratic making it a d8 metal. With four ligands, the complex can either be tetrahedral or square planar, though not seesaw (with four identical weak-field ligands, why have one axial angle be 180∘ but all the others be only ~90∘ or ~120∘? It makes more symmetrical sense to distribute the energy more evenly than that). LIGAND FIELD STRENGTH
