A 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)Bi-2(pzdc)(4)]center dot 2H(2)O (1, pzdc(2-) = pyrazine-2,3-dicarboxylate; Imi = imidazolium cation), crystallizes in the monoclinic space group, P2(1)/c (a = 14.3725(7) angstrom, b = 22.4499(10) angstrom, c = 11.5204(6) angstrom, and beta = 91.1183(16)degrees), 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 x 10(-6) S center dot cm(-1) at 85 degrees C and 95% RH.
