We report two cationic silver‐based coordination polymers with N‐donating quinoxaline as the linker. [Ag(quinoxaline)+] [–O3S(CH2)2SO3–]0.5·2H2O (which we denote as SLUG‐37 for University of California, Santa Cruz, structure No. 37; quinoxaline = C8H6N2) and [Ag(quinoxaline)+][CH3CO2–] (SLUG‐38) were solved by single‐crystal X‐ray diffraction and further characterized by several solid‐state techniques. Both structures consist of cationic 1D Ag‐quinoxaline chains arranged into π‐stacked layers, with charge‐balancing anions residing in the interlamellar space. The materials can be synthesized hydrothermally as well as in higher yield by reflux or room temperature conditions. The luminescent behavior of SLUG‐37 exhibits a strong white emission making it potentially useful as white LEDs.
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.
