Abstrakt: 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−, [ Ar 3 Sb (CH 2) 4 I ] + I − , [ Ar 3 Sb (CH 2) 4 SbAr 3 ] + I 2 − , where Ar = 2,6-(OMe)2C6H3. The complexes [ Ar 3 SbCH 2 C (O) OEt ] 2 + [ Hg 2 I 6 ] 2 − and [ Ar 3 SbMe ] 2 + [ HgI 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. [ABSTRACT FROM AUTHOR]
