摘要

In the title salt, [Ni(C26H24P2)2](CF3SO3)2 or [Ni(dppe)2]²⁺·(OTf⁻)2 [dppe = 1,2-bis(diphenylphosphanyl)ethane and OTf⁻ = trifluoromethanesulfonate], the Ni atom (site symmetry ) has a square-planar geometry with the bidentate ligands chelating the metal. As a result of the steric hindrance of the phenyl rings, the counter-ions are blocked from the metal coordination sphere. The dynamic disorder of the anion existing at 296 K is reduced at 100 K and based on these two temperatures, negative thermal expansion behaviour is observed.
