The synthesis and magnetic properties of a linear mixed-valence [Ni₃]⁵⁺ in an anthyridine tri-nickel complex

A novel trinuclear complex [Ni3(μ3-dbay)4Cl2]I3 (1) with a mixed-valence state was prepared by reacting the tridentate ligand 1,13,14-triaza-dibenz[a,j]anthracene (dibenzanthyridine = dbay) with anhydrous NiCl2 and sodium tetraphenylborate.
