Deduce the structure of [Nicl_(4)]^(2) and [Ni(Cl_(4)]^(2-) considering the hybridization of the metal. Calculate the magnetic moment (spin only) of the species.

Answer»

Solution : `[NiCl_(4)]^(2-) implies sp^(3)` (as `cl^(-)` is weak FIELD ligand) - Tetrahedral
`[Ni(CN)_(4)]^(2-)implies dsp^(2)` (as `CN^(-)` is strong field ligand) - SQUARE planar MAGNETIC moments
`(mu_(spin))`values are as follows,
`[NiCl_(4)]^(2-)impliessqrt(2(2+2))=2.82 B.M.`
`[Ni(CN)_(4)]^(2-)implies sqrt(0(0+2)) = 0.0 B.M.`
