The syntheses, structures, and magnetic properties of the compounds of formula [Fe^III(sal₂trien)]₂[Mn^II₂(ox)₃]·4H₂O·C₃H₇NO (1) and [In^III(sal₂trien)]₂[Mn^II₂(ox)₃]·3H₂O·CH₃OH (2) are reported. The structure presents a homometallic 2D honeycomb anionic layer formed by Mn^II 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.
