The crystal structure of EuRu(4)P(12) is isotypic with filled skutterudite structures of rare earth transition metal poly-phosphides: RFe(4)P(12) (R = Ce, Pr, Nd, Sm and Eu), RRu(4)P(12) (R = La, Ce, Pr and Nd) and ROs(4)P(12) (R = La, Ce, Pr and Nd). The Ru cation is coordinated by six P anions in a distorted octa-hedral manner. The partially occupied Eu position (site occupancy 0.97) is enclo...

Abstract Five different unsupported transition metal phosphides were synthesized and tested for hydrodeoxygenation of phenol in gas phase at 300 °C atmospheric pressure. The phosphide phases two steps: synthesis phosphates temperature programmed reduction. In situ X-ray diffraction reduction revealed the formation phases: Ni2P, MoP, CoP/CoP2, FeP WP. diffractograms showed that phosphate precurs...

The synthesis of InP nanofibers via a new Ullmann-type reaction of indium nanoparticles with tri(m-tolyl)phosphine (P(PhMe)(3)) was typically performed to illustrate an alternative route for the preparation of nanostructured metal phosphides, including III-V (13-15) and transition-metal phosphides. Triarlyphosphine compounds such as other two tri(m-tolyl)phosphine isomers, diphenyl(p-tolyl)phos...

BACKGROUND Metallic phosphides are extremely toxic pesticides that are regulated in their usage. Information concerning the impact of metallic phosphides on human health is abundant. Data regarding the clinical pathology of phosphide poisoning in humans or domestic and wild animals is largely incomplete with only a few cases of metallic phosphide poisoning being reported every year, especially ...

Reactions of primary imidazolio-phosphides (“imidazolylidene-phosphinidenes”) with R2SnCl2 yield as main products spectroscopically detectable Lewis pairs which undergo base-induced dehydrochlorination in the presence excess dichlorostannane to afford zwitterionic chloride adducts distannylated imidazolio-phosphines. In contrast, reactions R3SnCl proceed under dismutation furnish mixtures conta...
