Abstract

The interaction of penta(para-tolyl)antimony with oximes and carboxylic acids in benzene synthesized oximates and carboxylates of tetra(para-tolyl)antimony p-Tol₄SbX (X = ON=CHR, R = CHCHPh (1), С₆H₄(Br-3) (2); X = OC(O)R', R' = CH₂OС₆H₃Cl₂-2,4 (3), CF₂CF₂C(O)OH (4). The structure of compounds 1–4 was established by X-ray diffraction analysis (XRD). According to XRD data, the antimony atoms in complexes 1–3 have the coordination of a distorted trigonal bipyramid with three aryl ligands in the equatorial plane, while the CSbO axial angles are 178.94(5)°, 174.4(2)° and 176.95(5)°. Crystal 4 consists of distorted tetrahedral cations of tetra(para-tolyl)stibonium (CSbC angles 106.6(2)°−112.46(19)°) and singly charged anions of tetrafluoroethanedioic acid. Complete tables of atomic coordinates, bond lengths, and bond angles for compounds 1, 2, 3, 4 have been deposited at the Cambridge Crystallographic Data Center (CCDC 2130472, 2131085, 2131084, 2126158; deposit@ccdc.cam.ac.uk; http://www.ccdc.cam.ac.uk).

四(对甲苯基)锑衍生物的合成及结构特征

摘要

五(对甲苯基)锑与苯中的肟和羧酸相互作用合成四(对甲苯基)锑的肟酸盐和羧酸盐p -Tol ₄ SbX (X = ON=CHR, R = CHCHPh ( 1 ), С ₆ H ₄ (Br-3) ( 2 ); X = OC(O)R', R' = CH ₂ OС ₆ H ₃ Cl ₂ -2,4 ( 3 ), CF ₂ CF ₂ C(O)OH ( 4 ). 化合物1 – 4的结构通过X射线衍射分析(XRD)建立。XRD数据显示，配合物1 ~ 3中的锑原子在赤道面与三个芳基配体形成扭曲的三角双锥配位，CSbO轴角分别为178.94(5)°、174.4(2)°和176.95( 5）°。晶体4由四(对甲苯基)锑的扭曲四面体阳离子(CSbC角106.6(2)°−112.46(19)°)和四氟乙二酸的单电荷阴离子组成。化合物1 , 2 , 3 , 4的原子坐标、键长和键角完整表已保存在剑桥晶体学数据中心（CCDC 2130472、2131085、2131084、2126158；deposit@ccdc.cam.ac.uk；http://www.ccdc.cam.ac.uk）。
