“…34 This was highlighted in our initial work on HgTe, where the reaction of HgBr 2 and trioctylphosphine telluride in a solution of amines-TOPO yielded Q-HgTe. 13 The same reaction without TOPO reportedly yields a cyclic Hg-Te complex, 35 which we assumed was rapidly formed and decomposed almost instantaneously, yielding the nanoparticles. However, an examination into potential mechanisms explores the essential role of the surfactant in nanoparticles synthesis and highlights that the passivating ligands react with the monomer providing a key step in nanoparticle synthesis.…”

“…The precursors were chosen whilst referring to the work of Huang et al, avoiding toxic metal alkyls or tellurium sources. 18 The reaction between mercury(II) bromide and tri-n-octylphosphine telluride (TOPTe, a proven source of Te 0 ) in a hot coordinating solvent is thought to proceed rapidly via the intermediate (HgBr 2 ) 4 ? (TeP(C 8 H 17 ) 3 ) 3 to nanosized HgTe, as described by Huang, although this has not been proved experimentally due to the rapid reaction.…”

Se, Te) particles are an important class of materials that may have applications in the opto-electronics industry, notably as potential replacements for rare-earth dopants in optical fibers or in opto-electronic modulators. Organometallic routes to nanoparticles can produce materials of a superior quality, but often require highly toxic precursors, such as metal alkyls. We report here, for the first time, a simple route to organically passivated HgTe nanoparticles, which avoids the use of compounds such as dimethylmercury. This method can be used to prepare a wide range of HgE nanomaterials.

Reactions of the bicyclic silicon(I) ring compound [Si 4 {N(SiMe 3 )Dipp} 4 ] 1 with the chalcogens O 2 , Se, Te and the group 16 element compounds TeP(nBu) 3 and Me 3 NO afforded unprecedented amido-substituted cage compounds such as [Si 4 Se 3 {N(SiMe 3 )Dipp} 4 ] 3-5 with two different tricyclo-heptane-[a]type cages and one with a defect-hetero-cubane-type Si 4 Se 3 core, and [Si 4 Te 6 {N(SiMe 3 )Dipp} 4 ] 6 with an adamantane-type cage. These compounds were examined by single-crystal X-ray diffraction, multinuclear NMR spectroscopy in solution, ESI mass spectrometry, UV/Vis spectroscopy, and DFT calculations.Si 4 Se 6 (Thex) 4 (Thex = 1,1,2-trimethylpropyl) is known with type II and type III cores. [11,12] In general, compounds with type II core can be converted to compounds with type III topology under thermal treatment. [11,12] By contrast, silicon tellurium compounds decorated by organic substituents are rare. Only the silatellurane with type III structural motif Si 4 (CH 2 ) 2 Te 4 Me 4 ·CDCl 3 was described with two methylene groups and four Te atoms at the two-coordinate positions in the adamantane-type cage (III) synthesized by the reaction of the disilylmethane CH 2 (SiMeCl 2 ) 2 with Li 2 Te. [13] In general, cage compounds with Si-Te bonds are scarce due to the high sensitivity of these compounds towards air and moisture. [14] Eur.
