| Abstract: Under hydrothermal condition, a novel coordination polymer [Pb(C4H4O6)]n has been successfully synthesized by reaction flexible racemic ligand D,L-tartaric acid (C4H4O6) and Pb(Ⅱ)(NO3)2. Its structure is determined by single-crystal X-ray diffraction analysis and further characterized by X-ray powder diffraction, IR, CHN and TG analyses. It crystallizes in tetragonal, space group I41/acd with a=1.569 0(2) nm, c=1.009 5(2) nm, V=2.485 0(7) nm3, Z=16. Its structure contains left- and right-handed helical chains. Such helical chains with opposite chirality are alternatively arranged and further connected to form a three-dimensional framework. Topology analysis shows that it presents rare ecl topological structure. CCDC: 771026. | |
