摘要:Bis(tricyclohexyltin) pimelicarboxylate,[(CH2)5(CO2SnCy3)2](1),has been synthesized by the reaction of tricyclohexyltin hydroxide with pimelic acid and characterized by means of IR,1H and 13 C NMR,elemental analysis and X-ray diffraction.Complex 1 crystallizes in triclinic space group P1 with a=11.569(3),b=12.0419(2),c=17.3988(4) ?,α=81.4310(10),β=79.8270(10),γ=69.7060(10)o,V=2227.60(9) ?3,Z=2,C43H76O4Sn2,Mr=894.42,Dc=1.333 g·cm-3,μ=1.157 mm-1,F(000)=932,GOOF=1.339,the final R=0.0452 and w R=0.1333 for 6709 observed reflections(I > 2σ(I)).Complex 1 shows discrete dimeric structures and the tin atoms have a distorted tetrahedral geometry.The 1D chain structure of complex 1 is formed by intermolecular Sn···O interactions.Complex 1 displays good thermal stability under 553 K and has selective antibacterial property.Complex 1 is strong in vitro anti-tumor activity against five human tumor cell lines,Colo205,Hep G2,MCF-7,Hela and NCI-H460,and is significantly higher than that in the clinical use of carboplatin.
