A CdII-based coordination polymer with the formula [Cd(BIBT)(3,4-TDC)]n (JXUST-27, BIBT = 4,7-bi(1H-imidazol-1-yl)benzo-[2,1,3]thiadiazole and 3,4-H2TDC = thiophene-3,4-dicarboxylic acid) was synthesized under solvothermal condition. Single-crystal structural determination reveals that JXUST-27 takes a...
