single crystalX-ray diffraction analysis. The structural analysis reveals that complex 1 is a 2D-polymer containing interconnected 24-membered (Sn4O8C10Se2) macrocyclicrings. Unlike complex 1, the 2D polymer structure of complex 2 is made up of the typical ladder tetraorganodistannoxane unit containing 32-membered (Sn4O8C16Se4) macrocyclicrings. Complex 3 is a 3D corrugated polymeric structure in which
2,2'-硒二乙酸与相应的氯化有机锡(IV)与乙醇钠在乙醇中的反应或通过溶剂热合成路线的反应,得到了四种有机锡聚合物,即[(Me 3 Sn)2 Se(CH 2 COO)2 ] ñ(1),[(ME 2 Sn)的2硒(CH 2 COO)2(μ 3 -O)] ñ(2),[(卜3 Sn)的2硒(CH 2 COO)2 ] n(3)和[(Bu 2 Sn)Se(CH 2 COO)2 ] n(4)。通过元素分析,FT-IR,NMR(1 H,13 C和119 Sn)光谱和单晶X射线衍射分析对所有配合物进行了全面表征。结构分析表明,配合物1是包含相互连接的24元(Sn 4 O 8 C 10 Se 2)大环的2D聚合物。不同于复杂1,复杂的2D聚合物结构2由典型的梯形四有机二锡高氧烷单元组成,该单元包含32元(Sn 4 O 8 C 16 Se 4)大环。配合物3是3D波纹状聚合物结构,其中去质子化的二羧酸通过四

[Pt(en)OOC(CH2)nSe}2]. These complexes were characterized by microanalyses and NMR spectroscopy (1H, 13C1H}, 77Se1H} and 195Pt1H}). The seleno ligand in [Pt(N^N)(OOC(CH2)nSe(CH2)nCOOH)][OH] is coordinated to platinum through one carboxylate group and a selenium atom. The molecular structure of [Pt(en)(OOCCH2SeCH2COOH)][OH] was established by single crystal X-ray diffraction analysis. The reactivity

(OA)-linked disulfide, thioether, or selenium ether derivatives was synthesized, and their antiproliferative activity was evaluated against human liver cancer (BEL-7402 and HepG-2), colon cancer (HCT116), and normal liver (L02) cell lines using methyl thiazolyl tetrazolium assay (MTT). Preliminary bioassay results revealed that OA derivatives modified at the C3−OH position, i. e., compound a4 containing
