The complex [Ni(CN)4]2- is diamagnetic and the complex [NiCl4]2- is paramagnetic. What can you conclude about their molecular geometries? |
Both complexes have square planar geometries. Both complexes have tetrahedral geometries [NiCl4]2- has a square planar geometry while [Ni(CN)4]2- has a tetrahedral geometry. [NiCl4]2- has a tetrahedral geometry while [Ni(CN)4]2- has a square planar geometry. |
[NiCl4]2- has a tetrahedral geometry while [Ni(CN)4]2- has a square planar geometry. |
[Ni(CN)4]2− is a square planar geometry formed by dsp2 hybridisation and not tetrahedral by sp3. In [NiCl4]2−, there is Ni2+ ion, However, in the presence of weak field Cl− ligands, NO pairing of d-electrons occurs. Therefore, Ni2+ undergoes sp3 hybridization to make bonds with Cl− ligands in tetrahedral geometry.
