dc.description.abstractEnThree heterobimetallic MnIIIFeII complexes: [Mn(5-Br-salpn)(H2O)]2[Fe(CN)5NO]2H2O (1), [{Mn(salen)}2Fe(CN)5NO]2H2O (2) and [{Mn(saltmen)}4Fe(CN)5NO](ClO4)2H2O2CH3OH (3), have been synthesized by the reactions of MnIII/Schiff–base (SB) complexes, [Mn(SB)(H2O)]+, (SB being salen2 =N,N0-ethylenebis(salicylideneiminato) dianion; 5-Br-salpn2 = N,N0-1,3-propylenebis(5-bromosalicylideneiminato) dianion or saltmen2 = N,N0-(1,1,2,2-tetramethylethylene) bis(salicylideneiminato) dianion) with the [Fe(CN)5NO]2building block. X-Ray diffraction analyses on single crystals reveal that 1 has a trinuclear molecular structure, 2 displays a two-dimensional (2D) network structure, and 3 possesses a new 2D network of MnIII dinuclear motifs. The magnetic measurements show that the interaction between the MnIII S = 2 spins through the [NRC–Fe–CRN] bridges is systematically of antiferromagnetic nature: J/kB = 0.95(5) K and J/kB = 1.15(5) K for 1 and 2, respectively, while the direct MnIII–MnIII interaction, in the {Mn2(saltmen)2} dinuclear units present in 3, is ferromagnetic with J/kB = +1.75(5) K. Due to the ST = 4 spin ground state of these dinuclear units and the uniaxial magnetic anisotropy brought by the Mn(III) metal ions, 3 exhibits singlemolecule magnet properties. The 400–900 nm optical properties of the three compounds have been also investigated, showing no significant photoactivity unlike in the Na2[Fe(CN)5NO precursor
