YGYanlei GengYantai University JLJianfu LiYantai University QRQi RuiYantai University

Key Points

This research investigates how hydrostatic pressure affects the stability and chemical bonding of copper halides.
Applied hydrostatic pressure on Cu–X systems (X = F, Cl, Br, I)
Analyzed chemical bonding changes under compression
Investigated decomposition behavior of ionic compounds
Identified counterintuitive decomposition in copper halides under pressure
Demonstrated alterations in chemical bonding occur with increased pressure
Found pressure-induced destabilization varies by halide type (F, Cl, Br, I)

Abstract

Hydrostatic pressure profoundly alters chemical bonding and stability, yet it can also trigger counterintuitive decomposition in ionic compounds. In the Cu–X (X = F, Cl, Br, I) systems, we identify...
