The reproducible formation of a 3D oxalate based coordination compound of formula (NH4)5[MnII2CrIII3(ox)9]·10H2O, with an unusual MnII/CrIII ratio, is presented. The original topology of the anionic network leads to antiferromagnetic long-range ordering whereas its guests favour high humidity-dependent proton conductivity.
