A 3D hetero-metallic coordination polymer with an anionic rutile topological net decorated by polymeric cationic chains

The syntheses, X-ray crystal structures and topological analyses of a three-dimensional coordination polymer complex, {Cd(BTC)Na(H2O)3}n 1 (BTC3− = 1,3,5-benzenetricarboxylic anion), are reported. Complex 1 features a hetero-metallic framework built by alkali metal (sodium) and d10 metal (cadmium) with organic BTC. From a topological point of view, the whole structure can be considered as an anionic rtl (rutile) net constructed from Cd2+ and BTC3− decorated by polymeric cationic chains of [Na(H2O)3]n+.
