Well done Christian for his recent publication in Inorganic Chemistry

La2Sn2O7 is investigated under extreme conditions via laser heating in a diamond anvil cell with X-ray diffraction and Raman spectroscopy. DFT simulations support the experimental findings. A new ground state at 70 GPa that is recoverable to ambient conditions is revealed. The final state of the system is highly pathway dependent due to the covalent nature of the Sn−O bonding. Related La2Tc2O7 is simulated to determine the likelihood it has behavior analogous to that of La2Sn2O7
