Synthesis and single-crystal X-ray diffraction of novel high-pressure halides of d-elements (Fe and Y)

The aim of this proposal is to synthesize and study the crystal chemistry and high-pressure behaviour of transition metal's halides Me-Hal (Me = Fe or Y, Hal = F, Cl, Br, I) in diamond anvil cells at pressures up to 160 GPa by single crystal X-ray diffraction (SCXRD) at ID15b beamline, that will allow to produce new compounds and to understand how high pressure can alter their structures and tune physico-chemical properties. Moreover, the analysis of the phase diagrams of iron halides at high pressures may provide an opportunity to take an important step forward in understanding the missing halogen paradox in the Earth.
