Abstract: In the title compound, [Cd(C₈H₄O₄)(C₇H₆N₂)₃]_n, the Cd atom is seven-coordinated by four O atoms from two benzene-1,2-dicarboxylate (1,2-BDC) ligands and three N atoms from three benzimidazole ligands, resulting in a distorted pentagonal-bipyramid geometry. The 1,2-BDC ligands bridge the Cd atoms to form an extended helical chain structure. Neighbouring chains interact through - interactions, resulting in a two-dimensional structure.
