The hickel coördinátión compound bis(P,P-dialkylphosphinic-N-ethylamidato-N,S) nickel sounds complicated, but it's not too bad. The ligand P,P-dialkylphosphinic-N-ethylamidato- N,S (abbreviated SPR2N) is a bidentate ligand that forms coordinate covalent bonds to a Lewis acidic metal through its sulfur and nitrogen Lewis basic atoms as shown below: R. S. P.P-dialkylphosphinic-N-ethylamidato-N,S R Ligand abbreviation: SPR,N- H2C R = C(CH3)3 CH3 Ni(SPR N)2 is diamagnetic in the solid state. However, when Ni(SPR2N)2 is dissolved in solution, it is paramagnetic. Given that the coordinate covalent bonds remain intact in both the solid state and dissolved forms, provide an explanation for what may be occurring that
