Nickel and palladium both form complexes of the general formula M(PR 3 ) 2 Cl 2 .

Question:

Nickel and palladium both form complexes of the general formula M(PR₃)₂Cl₂. (The ligand PR₃ is a phosphine such as P(C₆H₅)₃, triphenylphosphine. It is a Lewis base.) The nickel(II) compound is paramagnetic whereas the palladium(II) compound is diamagnetic.
(a) Explain the magnetic properties of these compounds.
(b) How many isomers of each compound are expected?
