Abstract
Four heterotrimetallic complexes, {[Cu(L)Pr(H2O)4][Fe(CN)6]}2·2CH3OH·5H2O (1), {[Cu(L)Nd(H2O)4][Fe(CN)6]}2·CH3OH·6H2O (2), {[Cu(L)Sm (H2O)4][Cr(CN)6]·CH3OH·3H2O}n (3), and {[Cu(L)Gd(H2O)3][Fe(CN)6]·CH3OH·0.5CH3CN·2H2O}n [4; L = N,N′‐ethylenebis(3‐methoxysalicylideneiminato) dianion] were synthesized by a self‐assembly method and characterized structurally and magnetically. The results indicate that 1 and 2 are discrete hexanuclear clusters, whereas 3 and 4 form 1D regular chains and 2D networks, respectively. Interestingly, all of the structures possess the same structural inner core of CuII(L)–LnIII–MIII units, which can produce a variety of different structural forms. Magnetic measurements reveal that weak d–f magnetic coupling and the single‐ion magnetic effect of the LnIII ions both contribute to the final magnetic behavior.
