摘要以四苯基溴化锑和相应的吡啶- n -氧化物衍生物为原料合成了四苯基锑（2-巯基吡啶- n -氧化物）和四苯基锑（2-硒代吡啶- n -氧化物）。x射线晶体结构分析表明，前者在C2/c空间群中结晶。a为29.095(2)，b为10.6965(8)。(1) 18.134 c。β 94.154(5)和z8。巯基吡啶- n -氧化物配体通过其硫原子和氧原子结合，导致锑原子的八面体几何形状扭曲。硫和硒的四苯基锑吡啶n -氧化物衍生物被发现具有抗疟疾活性。
Abstract Tetraphenylantimony(2-mercaptopyridine-N-oxide) and tetraphenylantimony(2-selenopyridine-N-oxide) were synthesized from tetraphenylantimonybromide and the appropriate pyridine-N-oxide derivative. X-ray crystal structure analysis shows that the former compound crystallizes in space group C2/c. with a 29.095(2), b 10.6965(8). c 18.134(1). β 94.154(5) and Z 8. The mercaptopyridine-N-oxide ligand binds via both its sulfur and oxygen atoms, leading to a distorted octahedral geometry about the antimony atom. Tetraphenylantimonypyridine-N-oxide derivatives of sulfur and selenium were found to possess antimalarial activity.
