A novel complex [Pb(qina)2(DMSO)]·H2O was synthesized,of which qina-is the quinaldic acid radical and DMSO the dimethyl sulfoxide. Elemental analysis,IR spectra,and X-ray single-crystal diffraction were carried out to determine the composition and crystal structure. This complex belongs to monoclinic system,space group P121/n1,with a=7.1553(17),b=17.543(2),c=17.306(2) ,β=91.671(4)°,C22H20N2O6PbS,Mr=647.65,Z=4,V=2171.5(6) 3,Dc=1.981 g/cm3,μ=7.908 mm-1,F(000)=1248,–9≤h≤6,–23≤k≤19,–22≤l≤22,R=0.0221 and wR= 0.0488. Weak coordinate bond is formed between oxygen atom in DMSO and Pb(Ⅱ ) . There are also weak interactions,such as π-π interaction,hydrogen bonds and so on,among the complex molecules.
