Single source precursor route to nanometric tin chalcogenides

Low-temperature solution phase synthesis of nanomaterials using designed molecular precursors enjoys tremendous advantages over traditional high-temperature solid-state synthesis. These include atomic-level control over stoichiometry, homogeneous elemental dispersion and uniformly distributed nanoparticles. For exploiting these advantages, however, rationally designed molecular complexes having certain properties are usually required. We report here the synthesis and complete characterization of new molecular precursors containing direct Sn-E bonds (E = S or Se), which undergo facile decomposition under different conditions (solid/solution phase, thermal/microwave heating, single/mixed solvents, varying temperatures, etc.) to afford phase-pure or mixed-phase tin chalcogenide nanoflakes with defined ratios.

Synthesis, structural characterization and in vitro antiproliferative effects of novel organotin(iv) compounds with nicotinate and isonicotinate moieties on carcinoma cells

Novel triorganotin(iv) nicotinates and isonicotinates were successfully synthesized and fully characterized. The preliminary results for their in vitro antiproliferative activity against the mouse colon carcinoma C26 cell line are also reported.

Reactivity of a carbonyl moiety in organotin(iv) compounds: novel Pd(ii) and Cu(ii) complexes supported by organotin(iv) ligands

Converting the carbonyl moiety of an (aryl)organotin(iv) compound gives other functional groups that can act as metalloligands.

Experimental evidence for hypercoordination in triorganotelluronium halides with 2-(Me2NCH2)C6H4 groups

Triorganotelluronium halides of type [{2-(Me₂NCH₂)C₆H₄}_nPh_3−nTe]⁺X⁻ (n = 1–3, X = Cl, Br, I) were prepared and structurally characterized both in solution and in the solid state, showing a (C,N)-chelating behavior of the 2-(Me₂NCH₂)C₆H₄ groups.
