Hydrothermal synthesis of a one-dimensional Ni(II) coordination polymer with H-bonding left- and right-handed helical features

AbstractOne new coordination polymer has been synthesized hydrothermally under the intervention of Ni(II) salts, 4,4′-sulfonyldibenzoate (H2sdba) with neutral linkers 2,5-bis(4-pyridyl)-1,3,4-thiadiazole (bpt), formulated as: [Ni(bpt)(sdba)(H2O)3]n (1). X-ray structural analysis reveals that polymer 1 displays one-dimensional zigzag chain with alternating intersectional terminal sdba units. The interactions of 1 D chains by pseudo-watertapes result in the formation of 3 D supramolecular network. Interestingly, two types of hydrogen bonding left- and right-handed helices appear simultaneously in the mesomeric framework 1.
