Abstract: The title complex {[nBu2SnO2CCH(CS2NEt2)2]2O}2 was synthesized and characterized by elemental analysis, IR, NMR and Xray single crystal diffraction. The results show that the complex belongs to a monoclinic system with space group C2/c, and unit cell dimensions: a=2.848(5) nm, {b=1.381(2) nm}, c=3.239(6) nm, β=111.11(2)°, Z=4, V=11.884(35) nm3, D-c=1.329 g/cm3, {F(000)}=4 912, S=0.991, R-1=0.053 5, wR2=0.116 6. The complex has a centrosymmetric dimer structure mode with a fourmembered central endocyclic Sn2O2 unit. The endocyclic tin atoms are sixcoordination and have coordition geometry of distorted octahedron. The exocyclic tin atoms are fivecoordination and have coordination geometry of distorted trigonal bipyramid. This complex was tested in vitro against human tumour cell lines, MCF-7 and WiDr, and displayed the higher activity.
