Abstract: In the title compound, [CeCl₂(C₁₀H₈N₂O₂)₂(H₂O)₃]Cl·H₂O, each Ce^III atom is coordinated by six O atoms [Ce-O = 2.454 (3)-2.454 (3) Å] and two chloride ions [Ce-Cl = 2.8277 (9) and 2.8721 (9) Å] in a distorted tetragonal-antiprismatic geometry. One of the 4,4'-bipyridine N,N'-dioxide ligands acts as a bridging ligand while the other acts a terminal ligand, leading to the formation of a linear polymeric structure. In the crystal structure, adjacent polymeric chains are cross-linked by O-HO and O-HCl hydrogen bonds, forming a three-dimensional network.
