Organotin compounds are a recurring motif in organometallic chemistry. The syntheses and characterization of new diorganotin compounds with α-oxoglutaric acid isonicotinyl hydrazone are described, prepared compounds were characterized by elemental analysis, UV/Vis, 1H, and 13C NMR spectroscopy, and X-ray diffraction. They both have a distorted pentagonal bipyramidal arrangement, with a heptacoordinated
有机锡化合物是有机金属化学中反复出现的基序。描述了新的二有机锡化合物与α-酮戊二酸异烟酰腙的合成和表征,制备的化合物通过元素分析、UV/Vis、1H和13C NMR光谱以及X射线衍射进行了表征。它们都具有扭曲的五边形双锥排列,具有七配位的中心锡原子。化合物 1 呈现中心对称双核骨架。有趣的是,分子间 O–H…N 和 O–H…O 氢键有助于二维网络。化合物2是一个简单的单核化合物,它表现出由分子间O–H…Cl和N–H…O氢键构成的罕见的一维链。
