Abstract

The assembly reaction of a Mn(iii) salen-type dimeric complex, [MnIII2(saltmen)2(H2O)2](ClO4)2 (saltmen2− = N, N′-(1,1,2,2-tetramethylethylene)bis(salycylideneiminate)), and a Ni(ii) oximato complex, [NiII(pao)2(phen)] (pao = pyridine-2-aldoximate; phen = 1,10-phenanthroline), in the presence of NaBPh4 yielded a heterometallic chain of [MnIII2(saltmen)2NiII(pao)2(phen)](BPh4)2 (Mn2Ni-BPh4) having a [–MnIII–ON–NiII–NO–MnIII–(OPh)2–] repeating unit surrounded by a “zeolite-like” network of BPh4 anions. Thanks to such bulky ion-walls, each chain is not only structurally separated with a nearest inter-chain metal⋯metal distance of 14.4 Å (Mn⋯Ni) but also magnetically extremely well isolated. This magnetic isolation and the ferromagnetic interactions between S = 3 anisotropic units constituting the chain play key roles that induce single-chain magnet behavior in this system.
