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. 2011-10-05 00:00:00 host network 1.1 diffraction 3.0 K multifunctional bimetallic coordination network Ferromagnetic NH guest molecules cm functionalized channels strategy water molecules formula TC hosts ammonium cations High Proton Conduction Chiral material exhibits framework FrameworkA chiral proton conductivity room temperature
