In the title complex, {[Cu3（H2O）8（4,4′-bipy）2（smbdc）2]·6H2O}n Cu1 and Cu2 have different coordination environment. The 5-sulfo-1,3-benzenedicarboxylic acid （smbdc^3-） ligands form one-dimensional zigzag chains linked by Cu atoms. The two adjacent zigzag chains extend into one-dimensional ladder frameworks bridged by a secondary building unit [Cu（H2O）4（4,4＇-bipy）2]^2＋. The hydrogen-bond interactions between chains make the complex a three-dimensional open supramolecular network.
