Which one of the following has a square planar geometry? (At. no. Co = 27, Ni = 28, Fe = 26, Pt = 78 — Coordination Compounds Chemistry Question

💡 Solution & Explanation

Cl– is a weak field ligand Hence, the compounds having chlorine is generally a high spin complex and the CFSE of the transition metal complexes is in the order 3d<4d<5d which means that the metal belong to high in the series will form a low spin complex. Among the given complexes Pt will form a low spin complex. Hence, the correct answer is option (d)
