Abstract

The assembling of [Mn(5-MeOsalen)(H2O)]+ and [(PzTp)Fe(CN)3]- yielded the zigzag chain [(PzTp)Fe(CN)3Mn(5-MeOsalen)·CH3CN]n (1) (PzTp- = tetrakis(pyrazolyl)borate, 5-MeOsalen2- = N,N′-ethylenebis(5-methoxysalicylideneiminate)). Its intricate magnetic properties can be understood by corroboration of experimental data with the DFT magneto-structural analysis and the comparison with the related congener based on the simpler Tp ligand (Tp- = hydrotris(pyrazolyl)borate), having the same molecular and supramolecular topology. The system shows ferromagnetic Fe(III)-Mn(III) couplings along the cyanide bridges, a D < 0 zero field splitting (ZFS) parameter on Mn(III) and weak antiferromagnetic inter-chain coupling. The interplay of intra- vs inter-chain parameters determines subtle magnetic properties, such as a field induced tuning of the network magnetism.
