High-Pressure Na3(N2)4, Ca3(N2)4, Sr3(N2)4, and Ba(N2)3 Featuring Nitrogen Dimers with Non-Integer Charges and Anion-Driven Metallicity
Dominique Laniel, Bjoern Winkler, Timofey Fedotenko +12
Charged nitrogen dimers are ubiquitous in high-pressure binary metal-nitrogen systems. They are known to possess integer formal charges x varying from one through four. Here, we pr…
Novel hydrogen clathrate hydrate
Yu Wang, Konstantin Glazyrin, Valery Roizen +8
We report a new hydrogen clathrate hydrate synthesized at 1.2 GPa and 298 K documented by single-crystal X-ray diffraction, Raman spectroscopy, and first-principles calculations. T…
Pressure induced lattice expansion and phonon softening in layered
Pinku Saha, Bishnupada Ghosh, Aritra Mazumder +2
We report high pressure X-ray diffraction and a detailed systematic Raman measurements on sample, which is mechanically exfoliated from a single crystal. A few new Bragg pe…
Metallic Hydrogen Sublattice and Proton Mobility in Copper Hydride at High Pressure
Thomas Meier, Florian Trybel, Giacomo Criniti +9
Atomic and electronic structures of Cu2H and CuH have been investigated by high pressure NMR spectroscopy, X-ray diffraction and ab-initio calculations. Metallic Cu2H was synthesiz…
Novel rhenium carbides at 200 GPa
Saiana Khandarkhaeva, Timofey Fedotenko, Maxim Bykov +7
Laser heating of rhenium in a diamond anvil cell to 3000 K at about 200 GPa results in formation of two previously unknown rhenium carbides, hexagonal WC-type structured ReC and or…
Revisiting spin state crossover in (MgFe)O by means of high resolution X-ray diffraction from a single crystal
Konstantin Glazyrin, Saiana Khandarkhaeva, Leonid Dubrovinsky +1
(MgFe)O is a solid solution with ferrous iron undergoing the high to low spin state (HS-LS) crossover under high pressure. The exact state of the material in the region of the cros…
