dc.descriptionCrystalline materials, especially metal-organic coordination polymers (MOCPs) built from self-assembly of metal ions and organic ligands, have been investigated in the field of proton conduction [1–7]. Distinct from other conventional proton conducting materials, such as Nafion [8, 9] or polymers [10, 11], a well-defined structure and crystallinity in MOCPs permit accurate identification of relevant structural information crucial for understanding the proton-conduction routes and other mechanisms involved. However, the lability of metal-ligand bonds in most MOCPs, linked to the mismatch between the Lewis acid-base pairs based on the concept of Hard-Soft Acid-Base (HSAB) principle [12], limits their applications especially in the presence of moisture, variable pH, or high temperatures [13–15].en_US
dc.description.abstractA new highly water stable bismuth-containing coordination polymer is reported along with its structural characterizations as determined by single crystal and powder X-ray diffraction, elemental, and thermal analysis, featuring an orange-red photoluminescence, and proton conductivity. The compound, (Imi)2[Bi2(pzdc)4]·2H2O (1, pzdc2- = pyrazine-2,3-dicarboxylate; Imi = imidazolium cation), crystallizes in the monoclinic space group, P21/c (a = 14.3725(7) Å, b = 22.4499(10) Å, c = 11.5204(6) Å, and β = 91.1183(16)°), which contains 2D layers of Bi that are connected into a 3D supramolecular structure via extended hydrogen bond network. The interlayered voids are occupied by lattice water and imidazolium ions. Compound 1 is synthesized using an optimized, facile slow evaporation method leading to a water stable compound with a well-defined 1D hydrogen-bonded water feature along the crystallographic a-direction that lead to a proton conductivity of 8.41 × 10−6 S·cm−1 at 85 °C and 95% RH.en_US
