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.

In the title complex, [Fe(NCS)2(C4H2N6)2(H2O)2]n, the FeII atom is on an inversion centre and the 4,4′-bi-1,2,4-triazole (btr) group is bisected by a twofold axis through the central N—N bond. The coordination geometry of the FeII atom is elongated distorted FeN4O2 octahedral, where the cation is coordinated by two N atoms from the triazole rings of two btr groups, two N atoms from NCS− ligands and two water molecules. Btr is a bidentate ligand, coordinating one FeII atom through a peripheral N atom of each triazole ring, leading to a one-dimensional polymeric (chain) structure extending along [101]. The chains are further connected through a network of O—HN and C—HS hydrogen bonds.
