WebNi2+, in the presence of strong field ligands such as CN-forms a square planar complex. 2nd and 3rd row d8 metals form square planar geometry irrespective of the nature of the ligand: With Pd2+ (which already generates a strong field) even a weak field ligand such as Cl-leads to the formation of a square planar complex, for example, [PdCl 4] 2-. WebMay 12, 2015 · No two complexes will have exactly the same value for 10 D q. The value of 10 D q even depends strongly on the geometry: octahedral complexes have a much larger value of 10 D q than tetrahedral ones: 4.44 D q ( oct) ≈ 10 D q ( tet) The notation does not extend well to complexes in geometries other than octahedral or tetrahedral.
