摘要

通过氯化锑(III)与 2,4,6-三甲氧基苯基锂的反应,合成了三(2,4,6-三甲氧基苯基)锡啶,并确定了其与碘乙酸乙酯发生烷基化反应生成{[2,4,6-(MeO)3C6H2]3SbCH2C(O)OEt}I-СHCl3-0.5Н2О的可能性。Ar3Sb 分子和[Ar3SbCH2C(O)OEt]+阳离子(Ar = 2,4,6-(MeO)3C6H2 )中的锑原子分别具有扭曲的三叉金字塔配位[角度 CSbC 101.97(4)°]和四面体配位[角度 CSbC 104.5(2)°-113.6(2)°]。锶配合物的结构还受到分子间相互作用的稳定,其中涉及水分子(I--H 2.815、2.881 Å)和氯仿 C=O-Cl (3.141 Å), I-H (2.793 Å)。

Organoantimony Compounds: [2,4,6-(MeO)3C6H2]3Sb and {[2,4,6-(MeO)3C6H2]3SbCH2C(O)OEt}I·СHCl3·0.5Н2О: Synthesis and Structure

Organoantimony Compounds: [2,4,6-(MeO)3C6H2]3Sb and {[2,4,6-(MeO)3C6H2]3SbCH2C(O)OEt}I·СHCl3·0.5Н2О: Synthesis and Structure

By reacting antimony(III) chloride with 2,4,6-trimethoxyphenyllithium, tris(2,4,6-trimethoxyphenyl)stibine was synthesized and the possibility of its alkylation with ethyliodoacetate was established to form {[2,4,6-(MeO)3C6H2]3SbCH2C(O)OEt}I·СHCl3·0.5Н2О. Antimony atoms in the Ar3Sb molecule and the [Ar3SbCH2C(O)OEt]+ cation, Ar = 2,4,6-(MeO)3C6H2 have distorted trigonal pyramidal [angle CSbC 101.97(4)°] and tetrahedral [angle CSbC 104.5(2)°‒113.6(2)°] coordination, respectively. The structure of the stibonium complex is additionally stabilized by intermolecular interactions, which involve water molecules (I···H 2.815, 2.881 Å) and chloroform C=O···Cl (3.141 Å), I···H (2.793 Å).

期刊介绍: Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
