K5Ir: reduced iridium stabilized at high pressure

Alkali binary compounds offer a way to expand our understanding of the periodic table. Specifically, the redox inert nature of alkali cations, even within some intermetallic compounds, enables one to access exotic oxidation states. Iridium presents a test case, as it is the transition metal best positioned to form a tr...

Pressure-Induced Phase Transitions in Cr-Based Nitride Electrides

Density functional theory calculations were used to investigate pressure-induced structural phase transitions in the nitride electrides Sr3CrN3 and Ba3CrN3 with nominally Cr4+ (d2 configuration) cations. At ambient conditions, both compounds crystallize in the hexagonal P63/m structure and undergo a transition to the...
