  • The ambient pressure fcc phase of NaB H4 transforms into a tetragonal P- 421 c near 6 GPa and then into an orthorhombic Pnma phase above 8 GPa. While the structures of the cubic and tetragonal phases are known, the structural information for the orthorhombic phase was limited to the space group and cell parameters. Here, we present synchrotron powder diffraction data for NaB H4 collected in a diamond anvil cell up to 11.2 GPa. A BaS O4 -type structure of the orthorhombic high-pressure phase was… CONTINUE READING
