[{1,3,5‐(CH3)3H3C6}6Tl4][GaBr4]4 — Synthesis and Structure of a Mixed Mono‐ and Bis(arene)thallium Complex

Abstract: we found that the reaction only takes place in dichloromethane if triarylamine radical cations and hexachloroantimonate ions are simu/raneous/r present. If the triarylamine radical cations are generated electrochemically with perchlorate as counterion, no reaction occurs. If the reaction is carried out with 2,6-dimethylpyridinium hexachloroantimonate as the electrolyte, however, the reaction occurs without difficulty.

“…The use of acetonitrile as the solvent and weakly basic hexafluorometallates as counteranions favours the formation of mononuclear copper(1) cations, although only trimethylphosphine is a good enough ligand to compete with MeCN. Coordination of organic bases to thallium(1) is characteristically weak (18), and the isolation of ~1 ' salts containing ligated trimethylamine or PMe3 probably owes more to the low solubilities of the compounds than to any other reason. In both cases the ligands are lost readily from the solids on pumping at room temperature.…”

“…In binuclear di-thallium(I) bis[tetrabromo-gallium(III)] tris(1,3,5-trimethylbenzene) solvate (4) [22] one [GaBr 4 ] − anion bridges two thallium(I) centres, whereas the other is terminally bound, giving two independent thallium centres, each of which is associated with 1,3,5-trimethylbenzene molecules. The thallium forming four Tl···Br bonds is connected to one 1 In the binuclear structure of bis(μ 2 -2,6-dimethylphenolato)-bis(2,6-dimethylphenolato)-di-tin(II).2(toluene) (7) [25], two centrosymmetrically related molecules associate via Sn(lp)···π(aryl) interactions [d = 3.36 Å and θ = 10.8°] to form a dimeric, zero-dimensional aggregate.…”

“…Chemical diagrams for these and for two further structures featuring Sb(lp)···π(arene) interactions in the crystal structures, (22) and (23), are shown in Figure 14.10. Although the common feature of (18)- (21) is the presence of mononuclear species, in trichlorido-antimony toluene (18) [38] and tribromidoantimony(III) mesitylene (19) [39] solvate a single interaction occurs between antimony(III) and the solvent molecule.…”

“…[12] Given that it has four donor atoms an M 2 L 3 4 was easily prepared, [13] but the FAB mass spectrum (Figure 1) crystal structure of 1 (Figures 2 and 3) showed it to be a tetrahedral complex in which each metal ion occupies the vertex of a tetrahedron, and each ligand, acting as a bridge between two metal ions, spans one edge of the tetrahedron. [14] Multiple p-stacking interaction between ligands is evident ( Figure 2).…”
