In the title compound, [Ba{HOOC(C6H4)2CO2}2(H2O)2] or [Ba(C14H9O4)2(H2O)2], the Ba atoms are coordinated by nine O atoms, six from two 2′-carboxybiphenyl-2-carboxylate (Hbpdc−) ligands and three from three coordinated water molecules, resulting in the formation of face-sharing distorted monocapped square antiprisms. The Hbpdc− ligands bridge the Ba atoms to form a one-dimensional helical polymer, with a Ba
Ba distance across the chain of 4.1386 (17) Å. Adjacent chains are parallel to each other. The two independent ligands are tetradentate and have the same coordination mode, exhibiting μ-oxo bridges and η8-chelation. The crystal structure is further stabilized by hydrogen bonds within each chain.
