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)°.
