Coordination polymers (CPs) have attracted increasing interest in recent years. In this work, two new CPs, namely poly [[aquabis(2,2 0 -bipyridine-2 ] sesquihydrate], {[Mn(C 16 H 10 O 7 )(C 10 H 8 N 2 )]Á1.5H 2 O} n (2), have been prepared using the tricarboxylic acid 5-[(4-carboxyphenoxy)methyl]benzene-1,3-dicarboxylic acid and 2,2 0 -bipyridine under hydrothermal conditions. CP 1 displays a twodimensional layer structure which is further extended into a three-dimensional (3D) supramolecular structure via intermolecularinteractions, while CP 2 shows a different 3D supramolecular structure extended from one-dimensional ladder chains by intermolecularinteractions. In addition, the solid-state luminescence spectra of 1 and 2 were studied at room temperature.
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.
