中文摘要	Three cyanide-bridged dodecanuclear macrocyclic wheel-like complexes [Cr(bpmb)(CN)(2)](6)[Mn(5-Brsalpn)](6)center dot 12H(2)O (1), [Co(bpmb)(CN)(2)](6)[Mn(5-Brsalpn)] 6 center dot 12H(2)O (2) and [Co(bpmb)(CN)(2)](6)[Mn(5-Clsalpn)](6)center dot 24H(2)O center dot 8CH(3)CN (3) [bpmb(2-) = 1,2-bis(pyridine-2-carboxamido)-4-methylbenzenate dianion; 5-Brsalpn(2-) = N,N'-propylenebis(5-bromosalicylideneaminato) dianion; 5-Clsalpn(2-) = N, N'-propylenebis(5-chlorosalicylideneaminato) dianion] have been synthesized and their crystal structures and magnetic properties have been investigated. The three compounds are structurally isomorphous and consist of alternating Mn(III)-Schiff base cations and [M(bpmb)(CN)(2)](-) anions, generating cyanide-bridged nanosized dodecanuclear macrocyclic structures with an approximate diameter of 2 nm. The study of the magnetic properties of complex 1 reveals an antiferromagnetic interaction between the Cr(III) and Mn(III) ions through the cyanide bridges. A best-fit to the magnetic susceptibility of the complex leads to a magnetic coupling constant of J(CrMn) = -2.65(6) cm(-1) on the basis of a one-dimensional alternating chain model with the Hamiltonian H = -J(CrMn)Sigma(N)(j=0) S-j .
