Abstract:
Two coordination polymers with mixed‐ligands, [ZnL(2,2′‐bipy)H 2 O] n ( 1 ) and [CdL(2,2′‐bipy)] n ( 2 ), (L=3,3′‐thiodipropionic acid; 2, 2′‐bipy=2, 2′‐bipyridine) have been synthesized and structurally characterized. Crystal structures reveal that the synthesized complexes consist of a one‐dimensional single‐chain and a one‐dimensional double‐chain, respectively. A prominent feature of complex 1 is the formation of a vagarious double‐chain by two neighboring single‐chains interleaving with each other. It is interesting for complex 2 to assemble the double chain into a 2D ordered supramolecular structure via π···π stacking interactions. Moreover, elemental analysis, IR, and luminescent spectra of complexes 1 ‐ 2 were also determined. At room temperature, complex 1 exhibits an intense emission at 360 nm upon 328 nm excitation, while complex 2 exhibits an intense emission at 472 nm upon 457 nm excitation, which can probably be assigned to the intraligand ( π – π *) fluorescent emission.
