A new three-dimensional supramolecule,[H3N(CH2)3NH3]·[Pb2(SIP)2]·6H2O was synthesized under the hydrothermal condition.Its structure was determined with single crystal X-ray diffraction analysis and further characterized via XRD,IR,fluorescent spectrum and elemental analysis.The compound crystallizes in triclinic space group P1,with a=0.79946(16) nm,b=0.9881(2) nm,c=1.0343(2) nm,α=81.25(3)°,β=84.95(3)°,γ=68.13(3)°,V=0.7489(3) nm3, Z=1,R1=0.0226,wR2=0.0486,GOF=1.099.Along the direction,binuclear cluster units [Pb2(SIP)2]2-link to each other via O1 and O4 forming two-dimensional anionic layers,then these layers are stacked down the c axis and was further linked by N-H…O and O-H…O hydrogen bonds to build the three-dimensional supramolecular structure.Fluorescent spectrum of compound 1 shows that there are two strong fluorescent emission peaks at λ=349 nm and 393 nm and a weak fluorescent emission peak at 384 nm(λmax,excitation=236 nm).
