The diplienylsulffine-3,3'-disulfo-4,4'-dicarbolcylic acid (H4-DPSDSDC) ligand and its coordination polymers, [I(2Zn(C24116S3022)(H20)41 (1) and {[Cu3(p/3 0H)2(C2,4,11683012)(H20)3(1DMF)]-3(H20)}, (2) (C24116S3012 = dii)henylsulfone-3,31-disulfo-4,41-dicarl)ox)rlate), were synthe'zed. The Zn(H20)4 units in 1 are connected by DPSDSDC4 ligands to generate a one-dimensional (ID) chain, which is bridged by K-0 bonds associated with bridging water molecules and sulfonate groups to yield a two-dimensional (2D) layer. In 2, the ID hydroxyl -bridging Cu(II) chains are connected by DPSDSIIIC4- ligands to give a 2D layer. The 2D layers in 1 and 2 are further connected by interlayered hydrogen bonds to give three-dimensional (3D) frameworks. Compounds 1 and 2 have good conductivities of 1.57 X 10-4 and 5.32 X 10-5 S cm 1, respectively. Continuous well-defined hydrogen bonding networks associated with water molecules, sulfonate groups, and carbo3cylate groups were observed in compounds 1 and 2. Such hydrogen bonding networks provide hydrophilic domains and effective transfer pathways for protons. Here, we present elegant examples of a precise determination of the pathways for proton ransport.
