Three tetranuclear clusters [(TpMe,mt3)Fe(CN)3Mn(L)]2 (, L = 5-Clacphmen; , L = 5-Clsalen; , L = 5-MeOsalen; TpMe,mt3 = hydrotris(3-methyl-4,5-propylene-5-methylpyrazol-1-yl)borate) were prepared by assembling the fac-Fe tricyanide with the corresponding Mn Schiff bases. The assembled molecules are linked by cyanide and phenoxide bridges. Weak π-π contacts between molecules are evident in these clusters. Compounds exhibit slow relaxation of the magnetization. The phenoxide linkers mediate ferromagnetic coupling between the Mn centers, which is ascribed to the long axial Mn-O* length. The overall magnetic exchange coupling nature of the Fe-C[triple bond, length as m-dash]N-Mn route is accounted for by the important structural parameters of bridging pathways such as Mn-Ncyano length, Mn-Ncyano-Ccyano angle, and Ceq-FeMn-Neq (eq = equatorial) torsion angle.
