It would be an oxide of carbon (an oxocarbon), indeed a pentamer of carbon monoxide. As of 2000, the compound had yet to be synthesized in bulk, but there have been reports of trace synthesis.[2][3][4] Related compoundsCyclopentanepentone can be viewed as the neutral counterpart of the croconate anion {{chem|C|5|O|5|2−}}. The compound referred to in the literature and trade as "cyclopentanepentone pentahydrate" (C5O5·5H2O) is probably decahydroxycyclopentane (C5(OH)10).[3][5] References1. ^{{Cite web|url = https://pubchem.ncbi.nlm.nih.gov/summary/summary.cgi?cid=12305030&loc=ec_rcs|title = CID 12305030 - PubChem Public Chemical Database|work = The PubChem Project|location = USA|publisher = National Center for Biotechnology Information}} 2. ^{{ cite journal | last1 = Rubin | first1 = M.
