and if so, what are its properties?

Maybe it's CO₂-V, the polymer of CO₂, created over 33 GPa and 1700 K:

Wonderful article:

So far, once CO2-V has been created at high pressures and temperatures, it retains its structure at room temperature but only at pressures above 1 gigapascal. Below that pressure it collapses and is no longer a polymer.

So, at least in the form they've synthesized, it is not a good way to sequester CO₂.  It takes lots of energy to make, and isn't stable at room temp.

Interesting.
