A novel organo-tin compounds {[nBu2Sn（OOCC5H3（NO2）2）]2O}2 was synthesized by the reaction of 3,5-dinitrobenzoic acid with （n-Bu）2SnO. The structure was characterized by elemental analysis,IR spectroscopy as well as X-ray single crystal diffractometer. The crystal belongs to triclinic with space group Pī. Crystallographic date：a=1.0705（2） nm,b=1.3333（3） nm,c=1.4360（3） nm,α=68.892（3） °,β=78.297（3） °,γ=80.285（3） °,V=1.8620（7） nm3 ,Z=,dc=1.613 g/cm3 ,μ=1.406 mm-,F（000）=908,R1=0.0408,wR2=0.0948. The complex is a centrosymmetric dimer structure mode with a four-membered central endo-cyclic Sn2O2 unit in which two bridged oxygen atoms both connect with an exo-cyclic tin atom.
