Organotin(Ⅳ) complex {[(n-C4H9)2Sn(0.5·O2CCH2C12H8N)(0.5·C2H5O)]2O}2·(C12H8NH) was synthesized by the reaction of n-dibutyltin oxide with(9-carbazoly)-acetic acid.The complex was characterized by elemental analysis,IR and 1H NMR.The crystal structure was determined by X-ray single crystal diffraction.The crystal belongs to monoclinic,with space group C2/c with a=2.797 5(13) nm,b=2.153 4(10) nm,c=1.515 4(7) nm,β=118.759(6)°,V=8.003(7) nm3,Z=4,μ=1.285 mm-1,Dc=1.386 g/cm3,F(000)=3 408,R=0.057 1,wR=0.136 2,GOF=1.005.The complex is a centrosymmetric structure mode with a four-member 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 atoms are all five-coordination and have a coordination geometry of a distorted trigonal bipyramid.This complex was tested in vitro against human tumour cell lines,MCF-7 and WiDr,and displayed high activity.
