Abstract

It has been established that ethyl iodoacelate and 1,4-diiodobutane alkylate triarylantimony Ar₃Sb with the formation of [Ar₃SbCH₂C(O)OEt]⁺I⁻ and [Ar₃Sb(CH₂)₄I]⁺I⁻, \({[{\rm{A}}{{\rm{r}}_3}{\rm{Sb}}{({\rm{C}}{{\rm{H}}_2})_4}{\rm{I}}]^ + }{{\rm{I}}^ - },\;{[{\rm{A}}{{\rm{r}}_3}{\rm{Sb}}{({\rm{C}}{{\rm{H}}_2})_4}{\rm{SbA}}{{\rm{r}}_3}]^ {2+} }{\rm{I}}_2^ - \), where Ar = 2,6-(OMe)₂C₆H₃. The complexes \([{\rm{A}}{{\rm{r}}_3}{\rm{SbC}}{{\rm{H}}_2}{\rm{C}}({\rm{O}}){\rm{OEt}}]_2^ + \;{[{\rm{H}}{{\rm{g}}_2}{{\rm{I}}_6}]^{2 - }}\) and \([{\rm{A}}{{\rm{r}}_3}{\rm{SbMe}}]_2^ + \;{[{\rm{Hg}}{{\rm{I}}_4}]^{2 - }}\) · DMSO have been synthesized by the reaction of [Ar₃SbCH₂C(O)OEt]+I⁻ and [Ar₃SbMe]+I⁻ with mercury diiodide and studied by X-ray diffraction. The antimony and iodine atoms have a distorted tetrahedral coordination. The CSbC and IHgI angles are ranged within 103.28(14)°–116.68(14)°, 103.7(4)°–115.5(4)° and 98.122(9)°–125.590(12)°, 102.66(2)°–115.64(2)°, respectively.
