Abstract: In the title compound, {[La₂(C₁₀H₁₁N₂O₅S)₆(H₂O)₄]·2C₁₀H₈N₂·14H₂O}_n, the La^III ions are in a slightly distorted bicapped trigonal prismatic geometry, and are linked by six carboxylate groups in a syn-syn bidentate bridging fashion to form a one-dimensional inorganic-organic alternating linear chain. These polymeric chains generate microchannels extending along [100], and these cavities are occupied by discrete tetradecameric water clusters, which interact with their surroundings and finally furnish the three-dimensional supramolecular network via 15 O-HO, one O-HS, two O-HN and six N-HO classical hydrogen bonds. 4,4-Bipyridine acts as an inserting component and hydrogen-bond acceptor, and it is a nonplanar molecule with a dihedral angle of 33.12 (13)° between the pyridine rings. Owing to the numerous classical hydrogen bonds, the observed weak intermolecular C-HO, C-H and - stacking interactions can be neglected with regard to stabilizing the network.
