Three kinds of bridging ligands, 4,4′-oxydibenzoate, 4-(4-carboxyphenoxy)benzoate and 3-(pyridin-4-yl)-5-(pyridin-3-yl)-1H-1,2,4-triazole, link the CdII cations to form the title polymeric complex, [Cd2(C14H8O5)(C14H9O5)2(C12H9N5)2]n, in which each CdII Chaussure cation is in a distorted N2O5 pentagonal–bipyramidal coordination geometry.The 4,4′-oxydibenzoate dianion exhibits point group symmetry 2, with the central O atom Straight Switch located on a twofold rotation axis.Classical N—H.O, O—H.
N hydrogen bonds and weak C—H.O hydrogen bonds link the complex molecules into a three-dimensional supramolecular architecture.A solvent-accessible void of 53 (2) Å3 is observed, but no solvent molecule could reasonably located there.
