A Simple and Versatile Approach for the Low-Temperature Synthesis of Transition Metal Phosphide Nanoparticles from Metal Chloride Complexes and P(SiMe ).

Metal chloride complexes react with tris(trimethylsilyl)phosphine under mild condition to produce metal phosphide (TMP) nanoparticles (NPs), and chlorotrimethylsilane as a byproduct. The formation of Si-Cl bonds that are stronger than the starting M-Cl bonds acts as a driving force for the reaction. The potential of this strategy is illustrated through the preparation of ruthenium phosphide NPs using [RuCl (cymene)] and tris(trimethylsilyl)phosphine at 35 °C.

Synthesis and structures of homoleptic germylenes and stannylenes with sulfonimidamide ligands.

An unusual series of germylenes and stannylenes with homoleptic symmetric and unsymmetric -substituted sulfonimidamide ligands PhSO(NiPr)(NHiPr) 1 and PhSO(NMes)(NHiPr) 2 have been prepared by protonolysis reaction of Lappert's metallylenes [M(HMDS)] (M = Ge or Sn) with two equivalents of the appropriate sulfonimidamide. The homoleptic germylenes [PhSO(NiPr)]Ge 3 and [PhSO(NMes)(NiPr)]Ge 4, and stannylenes [PhSO(NiPr)]Sn 5 and [PhSO(NMes)(NiPr)]Sn 6 were fully characterized by NMR spectroscopy and by X-ray diffraction analysis. DFT calculations have been performed to understand the electronic properties brought by the sulfonimidamide ligand.

The five shades of oleylamine in a morphological transition of cobalt nanospheres to nanorods.

Understanding of cobalt nanorods' (Co NRs) formation still remains challenging when it comes to enhancing their anisotropic properties applicable in magnetic or catalytic areas. Herein, we propose a mechanism for the morphological transition from spherical cobalt nanoparticles (NPs) to Co NRs over time (9 h) in a mixture of [CoCl(PPh)] and oleylamine (OAm). In the literature, we described how spherical Co NPs are synthesized via a disproportionation process.

Symmetric and non-symmetric bis-metallylene iron complexes, precursors of iron germanide nanoparticles.

We report herein the synthesis of symmetric and non-symmetric bis-amidinato-germylene Fe(CO)3 complexes, as well as the preparation of the corresponding disymmetric germylene-stannylene and germylene-silylene complexes by selective displacement of a carbonyl ligand under UV-a light irradiation. The symmetric bis-germylene Fe(CO)3 complex has been applied in the synthesis of iron germanide nanocrystals.
