主　　题：hydrothermal carboxylate-sulfonate crystal chain structure 

摘      要：A new lead（Ⅱ） carboxylate-sulfonate has been hydrothermally synthesized and characterized by X-ray single-crystal and elemental analyses. It crystallizes in triclinic, space group Pi, with a = 8.1573（6）, b = 9.4663（7）, c = 12.7488（9）A, a = 89.2320（10）, β = 80.7380（10）, γ = 77.9760（10）°, Z = 2, V= 950.10（12） A^3, Mr= 599.57, Dc= 2.096 g/cm^3,μ = 9.032 mm^-1, F（000） = 572, the final R = 0.0412 and wR = 0.1035. It has a ID chain structure, and the Pb（Ⅱ） is six-coordinated. Two PbO6 polyhedra are interconnected via edge-sharing into a two-core unit. Such units are further interconnected by 3-sulfonato-benzoic acids into I D chains which are linked by hydrogen bonds into a layer structure. The 4,4＇-bipyridines are located at the interlayer space and link the layers into a supramolecular structure by π-π stacking interactions.
