It is a salt of the coordination complex [Ni2Cl2(en)4]2+ with chloride counterions. This blue solid is soluble in water and polar organic solvents. It is prepared by ligand redistribution from [Ni(en)3]Cl2{{hydrate|2}} and hydrated nickel chloride:[1] 2 [Ni(en)3]Cl2 + NiCl2 → 3 NiCl2(en)2 The rapid ligand redistribution is indicative of the kinetic lability characteristic of octahedral nickel(II) complexes.
