Carbon hexoxide
Carbon hexoxide or carbon hexaoxide is an oxide of carbon with an unusually large quantity of oxygen. The molecule has been produced and studied at cryogenic temperatures. The molecule is important in atmospheric chemistry and in the study of cold ices in the outer solar system and interstellar space. The substance could form and be present on Ganymede or Triton, moons in the outer solar system. The molecule consists of a six membered ring with five oxygen and one carbon atom, and one oxygen with a double bond with the carbon.〔
==Shape==
The molecule that has been observed has a Cs symmetry. The ring is not a flat hexagon but puckered with slightly different side lengths and angles (120°) from the regular hexagon. Going around the ring starting at the carbon to oxygen bond the interatomic distances are C-O: 1.362 Å O-O 1.491 Å O-O 1.391 Å O-O 1.391 Å O-O 1.491 Å O-C 1.362 Å. The angles between the bonds are: O-C-O 120.4°C-O-O 115.7° O-O-O 105.9 ° and the opposite from carbon O-O-O 104.1°. For the double carbon to oxygen bond, the length is 1.185 Å and the angle from the single bonds is 119.6°.〔
