Is it true that carbon dioxide can exist as a liquid at pressures above about 5.1 atmospheres?

Yes. A reference article states liquid carbon dioxide exists at pressures above 5.1 atm, and a 1978 planetary-science paper places the CO2 triple point at 5.1 bar where solid, liquid, or gas are stable phases.
