So I have a chain molecule made of carbon and oxygen, and I'm not sure what it would be called. Would any of you lovely fellows be able to help me?

molecule drawn badly on paint

The best name I've been able to come up with so far is "polyquadcarboxate" but I'm pretty sure this isn't right.

I'm looking for an IUPAC name if possible, but I suppose other names will do.

Thank you very much!

  • $\begingroup$ I'm looking for the name of the molecule itself, not what it would decompose to. But thanks anyway. $\endgroup$ Nov 11, 2015 at 19:35

    $\begingroup$ Giving names to non-existing entities is not IUPAC's primary interest. $\endgroup$ Nov 11, 2015 at 19:39

  • $\begingroup$ @querambique your compound could be called linear polymeric carbon dioxide $\endgroup$

The generic name is oxocarbon. In particular, "Carbon suboxide spontaneously polymerizes at room temperature into a carbon-oxygen polymer, with 3:2 carbon:oxygen atomic ratio." This is not quite the formula you provide, but the polymer has been synthesized.
