“…[35][36][37][38] To assess the strength of magnetic coupling we carried out a magnetic simulation using an alternating chain model (S Mn = 2 and S Fe = 1/2) derived by Seiden. [61][62][63] We also introduced a mean-field approximation (zj′) to the fitting equation to take into consideration the interchain magnetic interactions and/or zero-field splitting effect.…”

We synthesized six Fe(iii)-Mn(iii) bimetallic compounds by self-assembling the newly developed mer-Fe cyanide PPh[Fe(Clqpa)(CN)]·HO (1) and PPh[Fe(Brqpa)(CN)]·HO (2) with Mn Schiff base Mn(5-Xsalen) cations. These compounds include [Fe(Xqpa)(CN)][Mn(5-Ysalen)]·pMeOH·qHO [qpaH = N-(quinolin-8-yl)picolinamide; salen = N,N'-ethylenebis(salicylideneiminato) dianion; X = Cl, Y = H (3); X = Cl, Y = Br (4); X = Br, Y = H (5); X = Br, Y = F (6); X = Br, Y = Cl (7); X = Br, Y = Br (8)]. When precursor 1 was used, compounds 3 and 4 were isolated to give a dinuclear entity and a linear chain structure, respectively. The reaction of precursor 2 with the Schiff bases afforded four linear Fe(iii)-Mn(iii) chain complexes. Chain chirality with P- and M-helicity emerges in 4, 7, and 8, while 5 exhibits chain helicity opposite to the previous chain complexes and 6 presents no chain helicity. Such a structural feature is heavily dependent on the interchain π-π contacts and the Fe precursor bridging unit. Chiral induction from a local ethylenediamine link of Y-salen is propagated over the chain via noncovalent π-π interactions. All the bimetallic compounds show antiferromagnetic interactions transmitted by the cyanide linkage. A field-induced metamagnetic transition is involved in 4, 7, and 8, while a field-induced two-step transition is evident in 6. From a magnetostructural viewpoint, the coupling constant is primarily governed by the Mn-N-C angle (ax = axial) in the bimetallic chain complexes composed of mer-Fe(iii) tricyanides, although the torsion angle plays a role.
