Asymmetric compartmental proligands bearing adjacent N2O} and NSO} donor sets have been prepared and used in complexation reactions with nickel(II). [4-Methyl-2-[methyl-(2-pyridin-2-yl-ethyl)amino]methyl}-6-[(2-methylsulfanyl phenyl imino)methyl]phenol (HL3) and 2-[(3-dimethylamino-propyl)methylamino]methyl}-4-methyl-6-[(2-methylsulfanylphenyl imino)methyl]phenol (HL4) gave the dinuclear nickel(II) complexes, [Ni-2(L-3)(AcO)(NCS)(2)(CH3CN)] (3), Ni-2(L-4)(AcO)(2)(NCS)] (4), whereas 4-methyl-2-[methyl(2-pyridin-2-yl-ethyl)amino]-methyl}-6-[(2-methylsulfanylethylimino)-methyl]-phenol (HL5) and 4-methyl-2-[methyl(2-pyridin-2-yl-ethyl)amino]methyl}-6-[(3-methylsulfanylpropylimino) methyl]-phenol (HL6), gave the trinuclear nickel(II) complexes [Ni-3(L-5)(2)(OAc)(2)(NCS)(2)].2H(2)O (5) and [Ni-3(L-6)(2)(OAc)(2)(NCS)(2)].MeOH (6).
