摘要

Three cationic silver(I) coordination polymers, namely {[Ag-2(mu-bib)(3)](SO3CF3)(2)center dot(CH3CN)}(n) (1), [Ag(mu-bib)] (NO3)center dot(H2O)}(n) (2), and {[Ag(mu-bib)][BF4}(n) (3), have been prepared using flexible bis(imidazolyl)butane (bib) ligand and silver salts of different anions. All compounds are characterized by FT-IR, PXRD, elemental analysis, and single-crystal X-ray diffraction. Compound 1, containing triflate (SO3CF3-) anions, exhibits a two dimensional 6(3)-hcb network with an amazing ABCDEF packing mode of the single hexagonal layers. Compound 2, containing nitrate ions, forms a simple one dimensional wavy chain, while compound 3 with BF4- anions, shows a double helix DNA-shaped structure stabilized by Ag center dot center dot center dot Ag interactions between the two strands. The anions in the structures 1-3 are non-coordinating and participate in weak H-bonding, while imidazolyl rings are involved in pi center dot center dot center dot pi stacking interactions. Anion exchange experiments in aqueous solution, monitored by FT-IR and PXRD analyses, reveal interesting structural transformations. (C) 2019 Elsevier Ltd. All rights reserved.
