The reaction of Nil, with a tripodal hexadentate ligand (H3L = 1,1,1-tris(N-salicylideneaminomethyl)ethane) afforded the O-H . . .O bridged dinuclear [Ni-2(HL)(2)] complex. When Ni2+ was allowed to react with H3L in the presence of triethylamine (3 : 2 : 6), the linear trinuclear [Ni-3(L)(2)] complex formed, where the central nickel(II) ion is bridged by six phenolate oxygen atoms to the terminal nickel(II) ions.
