Abstract

New stybonium complexes containing polyanions have been obtained. Alkylation of tris(2,6-dimethoxyphenyl)stibine with ethyl iodoacetic acid synthesized [Ar₃SbCH₂C(O)OEt]I₃, Ar = 2,6-(MeO)₂C₆H₃, which is also the product of the reaction of [Ar₃SbCH₂C(O)OEt]I and I₂. The reaction of [Ar₃SbEt]I with mercury diiodide leads to {[Ar₃SbEt][Hg₃I₇]}_n, where Ar = 2,6-(MeO)₂C₆H₃. Compounds [Ar₃SbCH₂C(O)OEt]I₃ and {[Ar₃SbEt][Hg₃I₇]}_n were characterized by X-ray diffraction. Antimony and mercury atoms were found to have a distorted tetrahedral coordination. Bond angles are in the ranges: ∠CSbC 104.2(2)°‒113.9(1)° and ∠CSbC 102.4(4)°‒116.0(5)°, ∠IHgI 97.06(2)°–121.28(2)°.

锑配合物{[2,6-(MeO)2C6H3]3SbCH2C(O)OEt}I3和{[(2,6-(MeO)2C6H3)3SbEt][Hg3I7]}n的合成与结构

得到了新的含聚阴离子的stybonium配合物。三（2,6-二甲氧基苯基）辉己碱与碘乙酸乙酯烷基化合成[Ar3SbCH2C(O)OEt]I3, Ar = 2,6-(MeO)2C6H3，这也是[Ar3SbCH2C(O)OEt]I与I2反应的产物。[Ar3SbEt]I与二碘化汞反应生成{[Ar3SbEt][Hg3I7]}n，其中Ar = 2,6-(MeO)2C6H3。用x射线衍射对化合物[Ar3SbCH2C(O)OEt]I3和{[Ar3SbEt][Hg3I7]}n进行表征。发现锑和汞原子具有扭曲的四面体配位。键合角范围为：∠CSbC 104.2(2)°-113.9(1)°、∠CSbC 102.4(4)°-116.0(5)°、∠IHgI 97.06(2)°-121.28(2)°。
