Two new heterometallic Ni∥nCu∥(9-n) complexes [n = 1 (2) and 2 (3)] have been synthesized following a multicomponent self-assembly process from a n:(3 - n):2:6 stoichiometric mixture of Ni2+, Cu2+, L6-, and [CuL′]2+, where L and L′ are the bridging and blocking ligands 1,3,5-benzenetris(oxamate) and N,N,N′,N″,N‴-pentamethyldiethylenetriamine, respectively. Complexes 2 and 3 possess a unique cyclindrical architecture formed by three oxamato-bridged trinuclear linear units connected through two 1,3,5-substituted benzenetris(amidate) bridges, giving a triangular metallacyclophane core. They behave as a ferromagnetically coupled trimer of two (2)/one (3) S = ½ Cu∥3 plus one (2)/two (3) S = 0 Ni∥Cu∥2 linear units with overall S = 1 Ni∥Cu∥8 (2) and S = ½ Ni∥2Cu∥7 (3) ground states.
