Only stable in the crystal, the title compound 1 contains the first example of a polynuclear organoantimony cation. Interionic Sb···Sb and Sb···Br contacts are observed in 1, and reversible dissociation of 1 in solution gives the starting materials Mc2ShBr and Mc4Sb2. These components exchange Mc2Sb groups in the formation of 1.

The crystal structures of the complex 2 (1) and its precursors MeSbI2 (2) and I (3) are reported.In 1 there are tetrahedral cations and square pyramidal anions with Sb-1 distances of 290-320 pm.The structure of 2 contains MeSbI2 molecules.They associate via iodine bridges to form linear chains with alternating short and long Sb-1 distances.The coordination around antimony is distorted tetragonal pyramidal.The tetrahedral coordination of the ions in 3 results in the formation of a wurtzite type structure with antimony-iodine distances of 406 and 435 pm.The novel adducts Me3Sb*MeSbI2 (4) and Me2SbSbMe2*Me2SbBr (5) are formed by reaction of the components.They decompose easily with formation of antimony(V) compounds.Crystals of 5 are yellow but become reversibly black on cooling.

MeSbCl2 is formed by the exchange reaction of equimolar amounts of Me2SbCl with SbCl3.Alkylantimony dibromides of the type RSbBr2 with R = Me, Et, n-Pr, n-Bu are obtained by dismutation of the corresponding dialkylantimony bromides with SbBr3.Exchange as
