Sumario:The syntheses, structures, and magnetic properties of the compounds of formula [FeIII(sal2trien)]2[MnII2(ox)3]·4H2O·C3H7NO (1) and [InIII(sal2trien)]2[MnII2(ox)3]·3H2O·CH3OH (2) are reported. The structure presents a homometallic 2D honeycomb anionic layer formed by MnII ions linked through oxalate ligands and a cationic double layer of [Fe(sal2trien)]+ or [In(sal2trien)]+ complexes intercalated between the 2D oxalate network. The magnetic properties and Mössbauer spectroscopy of 1 indicate the coexistence of a magnetic ordering of the Mn(II) oxalate network that behaves as a weak ferromagnet and a gradual spin crossover of the intercalated [Fe(sal2trien)]+ complexes.
