The title complex {[(n-C8H17)2Sn(O2CCH2CS2NC4H8O)]2O}2 has been synthesized by the reaction of (mor- pholinylthiocarbamoylthio)acetic acid with the di-n-octyltin oxide in 1∶1 molar ratio. The complex was character- ized by elemental analysis, IR and 1H NMR. The crystal and molecular structure of complex was determined by X-ray single crystal diffraction. The crystal belongs to triclinic system with space group P1 and unit cell dimen- sions: a=1.2015(9) nm, b=1.4818(11) nm, c=1.8941(14) nm, α=72.485(10)°, β=88.586(10)°, γ=66.893(9)°, and Z=1, μ=1.034 mm-1, V=2.941(4) nm3, Dc=1.295 g·cm-3, F(000)=1196, R1=0.0588, wR2=0.1558. The complex is a centrosymmetric structure with a four-membered central endo-cyclic Sn2O2 unit in which two bridged oxygen atoms both connect with an exo-cyclic tin atom. The endo-cyclic tin atoms and the exo-cyclic tin atom are all five-coordinate and have coordination geometry of distorted trigonal bipyramid with an additional weak coordina- tion carboxylate oxygen. Four carboxylate ligands are divided into two types. And two of them are monodentate and connecting to each of exo-cyclic tin atoms by using one oxygen atom, whereas the others bridge to each pair of exo-and endo-cyclic tin atoms utilizing one oxygen atom.
