Abstract : The complex cation in the compound (Ni(tpen))-(CI04)2, MeNO2, where tpen denotes the quinquedentate ligand NNN'-tris(2-(2'-pyridyl)ethyl)ethylenediamine, was found (from its electronic spectrum and in its crystal structure) to be five covalent with all five nitrogen atoms of the chelate molecule bonded to the nickel atom in a somewhat distorted square pyramidal configuration.
