A complex-as-ligand strategy to get a multifunctional molecular material led to a metal–organic framework with the formula (NH<sub>4</sub>)<sub>4</sub>[MnCr<sub>2</sub>(ox)<sub>6</sub>]·4H<sub>2</sub>O. Single-crystal X-ray diffraction revealed that the anionic bimetallic coordination network adopts a chiral three-dimensional quartz-like architecture. It hosts ammonium cations and water molecules in functionalized channels. In addition to ferromagnetic ordering below <i>T</i><sub>C</sub> = 3.0 K related to the host network, the material exhibits a very high proton conductivity of 1.1 × 10<sup>–3</sup> S cm<sup>–1</sup> at room temperature due to the guest molecules.
