One-dimensional (1-D) zigzag chains of {[AgL]-(ClO 4 )•0.5Et 2 O} n (1), {[AgL](OTf)•Et 2 O} n (2), and {[AgL]-(BF 4 )•0.5CH 3 OH} n (3) were obtained from the reaction of AgClO 4 , AgCF 3 SO 3 , and AgBF 4 with 1,4-bis(pyridine-3-ylethynyl)benzene (L), respectively, in similar reaction conditions, whereas it led to the formation of a 1-D sinusoidal chain of {[AgL(NO 3 )]• H 2 O} n (4) and a metallolocycle of [Ag 2 L 6 ](BF 4 ) 2 (5) in a different reaction procedure for the AgNO 3 and AgBF 4 cases. Complexes 1−3 form 1-D zigzag chains, and every two chains are further stacked to give a pair of chains assisted by weak Ag(I)•••Ag(I) and π•••π interactions, whereas a single 1-D sinusoidal chain of 4 can only be obtained. Although the reaction is carried out in a similar reaction as 4 except that BF 4 − was used instead of NO 3 −, a metallocycle of 5 was obtained instead. It is noted that only the bridging L ligands in 5 adopt a syn conformation, whereas those in 1−4 are in an anti conformation. In this regard, this work has demonstrated the delicate effects of anions and reaction conditions on the assembly reactions of complexes 1−5. In addition, we observed a structural transformation during the heating process for 5. Although the powder X-ray diffraction pattern of 5 at 210 °C is similar to that of 3, it cannot be conclusively proven by powder X-ray diffraction studies at this moment due to the presence of some mismatches between both patterns of 5 and 3.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
