| Abstract: The lanthanide coordination polymer, Tb2(tda)3(H2O)2, and it′s single crystals was self-assembled from thiodiglycolic acid (H2tda) and corresponding terbium(Ⅲ) chlorides under hydrothermal conditions. Single-crystal structure shows that the compound presents a 2D network, an edge-sharing dinuclear polyhedral [Tb2O16] was found to be the building unit of the network, in which the eight-coordinated TbO8 and nine-coordinated TbO9 cores exhibit distinct coordination environments, that is, one is in a distorted monocapped square antiprism surrounding and the other is in a triply capped trigonal prism. The H2tda ligand exhibits two different coordination modes in framework, including mode a: Bis“syn, syn-bridging bidentate, chelating-bridging tridentate”, mode b: Bis“chelating-bridging bidentate, syn, anti-bridging bidentate”. Eventually, through the weak interaction, the networks formed 3D supramolecular architectures. Photoluminescence measurements indicate that the terbium compound is a strong green emitter in the solid state at room temperature. Crystal data for the complex: triclinic, space group P1, with a=0.794 66(8) nm, b=1.067 96(11) nm, c=1.433 23(14) nm, α=70.517 00(10)°, β=75.648 0(2)°, γ=76.975 0(2)°, V=1.097 26(19) nm3, and Z=2.
