Cyanide-Bridged Fe(III)−Mn(III) Chain with Metamagnetic Properties and Significant Magnetic Anisotropy

The assembling of [Mn(5-MeOsalen)(H2O)]+ and [(Tp)Fe(CN)3]- affords the one-dimensional zigzag chain [(Tp)Fe(CN)3Mn(5-MeOsalen)·2CH3OH]n [1; Tp- = hydrotris(pyrazolyl)borate and 5-MeOsalen2- = N,N‘-ethylenebis(5-methoxysalicylideneiminate)]. The corroborated experimental and ab initio data indicate ferromagnetic Fe(III)−Mn(III) couplings and D < 0 anisotropy on Mn(III). The field-induced metamagnetic behavior is due to interchain effects.
