The reaction of Ni2+ with a tripodal hexadentate ligand (H3L = 1,1,1-tris(N-salicylideneaminomethyl)ethane) and its 5-methoxy analog afforded the O-H...O bridged dinuclear [Ni2(HL)2] complexes. When Ni2+ was allowed to react with H3L in the presence of NEt3 (3:2:6), the linear trinuclear [Ni3(L)2] complex formed, where the central Ni(II) ion is bridged by six phenolate O atoms to the terminal Ni(II) ions. The prepn. of the NiII-MII-NiII (M = Mn, Co) heterotrinuclear complexes is also reported.
