【摘要】 目的合成广谱、高效、低毒的新型结构的有机锡抗癌化合物。方法利用二氯二丁基锡与对氯苯甲酰异羟肟酸反应,合成了有机锡化合物[(n-Bu)2Sn(C7H5O2Cl)-Cl]。通过元素分析、红外光谱及核磁共振谱进行了表征,并用X射线单晶衍射确定了该配合物的结构。结果显示该化合物为单斜晶系,空间群为P1,晶胞参数:a=1.4274(11)nm,b=1.5606(12)nm,c=1.7939(14)nm,α=94.551(15)°,β=92.862(14)°,γ=94.370(13)°,Z=8,V=3.965(5)nm3,F(000)=1760,1=0.0713,wR2=0.1736。结论目标化合物为五配位的畸变三角双锥构型。
【Abstract】 OBJECTIVE To synthesize diorganotin compound with more potent activity,less toxicity and broader spectrum.METHODS The title compound was synthesized by the reaction of dibutyltin dichloride with 4-chlorobenzohydrox-amic acid . The compound was characterized by elemental analysis, IR, 1HNMR spectra and X-ray single crystal diffraction. RESULTS The crystal of compound belongs to monoclinic symmetry with space group P1,a=1.4274(11) nm,b=1.5606(12)nm,c=1.7939(14)nm,α= 94.551(15)°, β= 92.862(14)°, γ= 94.370(13)°, Z=8,V=3.965(5)nm3, F(000)= 1760, R1=0.0713,wR2=0.1736. CONCLUSION The title compound was five-coordinated geometry of distorted trigonal bipyramid.
