Role of M-site cation in The Negative Linear Compressibility of Rutile-Like M II (dca) 2

Key Points

• This research aims to understand how different M-site cations affect the structural behavior of rutile-like materials under pressure.
• Utilized synchrotron high-pressure powder X-ray diffraction
• Analyzed structural changes in rutile-like network materials with M = Mn, Fe, Ni
• Conducted experiments at varying pressure conditions
• Observed negative linear compressibility in certain materials
• Identified distinct pressure-induced structural deformations related to M-site cations
• Noted variations in behavior among different metal cations (Mn, Fe, Ni)
