Data collected at 13-IDD (Advanced Photon Source, USA; beam FWHM, 3 × 3 μm2). a, The centre of the pressure chamber of the as-compressed ds-DAC. c, Re LP (low pressure): a = 2.5606(5) Å, c = 4.0588(12) Å and V = 23.047(7) Å3, that is, 149(3) GPa according to the equation of state from ref. 27, or 173(3) GPa according to ref. 3; Re HP (high pressure): a = 2.2214(3) Å, c = 3.5609(8) Å and V = 15.21(1) Å3, that is, 930(5) GPa27 or 1298(10) GPa3. b, After pulsed laser-heating at 2,200(200) K during 5 s. d, Re LP: a = 2.5577(3) Å, c = 4.1095(12) Å and V = 23.282(7) Å3, at 140(3) GPa27 or 162(3) GPa3; Re HP: a = 2.2297(2) Å, c = 3.5735(5) Å and V = 15.38(1) Å3, at 895(5) GPa27 or 1,250(10) GPa3; Re7N3: a = 6.3086(4) Å, c = 4.0048(7) Å and V = 138.04(4) Å3. Structural data for Re7N3 were taken from the results of single-crystal XRD data analysis.
