Urothermal Syntheses Of Chiral Zincic Benzotriazole-5-Carboxylate Frameworks For Lodine Uptake

So far, the synthesis of chiral framework with achiral organic ligand still faces great challenge. Herein three new coordinated complexes [Zn(btca)Cl]center dot DMA center dot N(CH3)(2) (1), [Zn(btca)(Ac-)center dot N(CH3)(2) (2) and [Zn(btca)]center dot H2O (3) (DMA = N,N-dimethylacetamide, btca = benzotriazole-5-carboxylate acid) were synthesis via different methods. Single-crystal X-ray diffraction analysis revealed that compounds 1 and 2 were isostructural and showed achiral layer with fes topology, and 3 presented a chiral three-dimensional framework with eta topology. The result of this work has demonstrated that urothermal synthesis will be promising means of constructing chiral framework with achiral building block. Compound 3 also displayed an excellent property of iodine uptake.
