Ethylenediamine complexes

chemical compound

coordination complex with the formula [CoCl2(en)2]Cl (en = ethylenediamine)

Dichlorobis(ethylenediamine)nickel(II) is the inorganic compound with the formula NiCl2(en)2, where en = ethylenediamine. The formula is deceptive: the compound is the chloride salt of the coordination complex [Ni2Cl2(en)4]2+. This blue solid is soluble in water and some polar organic solvents. It is prepared by ligand redistribution from [Ni(en)3]Cl2 and hydrated nickel chloride: 2 [Ni(en)3]Cl2 + NiCl2 → 3 NiCl2(en)2
