Heteropolynuclear [MnIICrIII] oxalate-bridged coordination compounds with dimethylethylammonium cation – influence of N-donors ligand

Proton conductivity has recently been regarded as a new functionality of the metal-organic compounds due to their crystallinity and high porosity as well design ability and tunability in structure and property. The simplest method to introduce proton carriers is to include a counterion such as hydronium (H3O+), ammonium [NH4+, (CH3)2NH2+, ...] or anion (SO42-), resulting in the charged compounds. The counterions form the hydrogen-bonding with the guest water or other constituents of compound, making proton-conducting pathways composed of hydrogen-bond networks. Conductivity can also be achieved by introducing of functionalized structural components such as non-coordinated groups in organic ligands (e.g., -OH, -NH2, -COOH or -SO3H) or by coordinating a metal center with functional molecules as H2O, EtOH, and imidazole.
