Cyclopropanetrione

Cyclopropanetrione or trioxocyclopropane is a little-known oxide of carbon with formula C₃O₃. It consists of a ring of three carbon atoms each attached to an oxygen atom with a double bond. Alternately it can be thought as a trimer of carbon monoxide. This compound is thermodynamically unstable, and has not been produced in bulk. However it has been detected using mass spectrometry.

It is the neutral equivalent of the deltate anion C₃O₃²⁻, known since 1975. An equivalent hydrate hexahydroxycyclopropane or cyclopropane-1,1,2,2,3,3-hexol, (-C(OH)₂-)₃ also exists. This contains geminal hydroxy groups.

Dioxane tetraketone

Dioxane tetraketone (or 1,4-dioxane-2,3,5,6-tetrone) is an organic compound with the formula C₄O₆. It is an oxide of carbon (an oxocarbon), which can be viewed as the fourfold ketone of dioxane. It can also be viewed as the cyclic dimer of oxiranedione (C₂O₃), the hypothetical anhydride of oxalic acid.

In 1998, Paolo Strazzolini and others synthesized this compound by reacting oxalyl chloride (COCl)₂ or the bromide (COBr)₂ with a suspension of silver oxalate (Ag₂C₂O₄) in diethyl ether at −15 °C, followed by evaporation of the solvent at low temperature and pressure. The substance is stable when dissolved in ether and trichloromethane at −30 °C, but decomposes into a 1:1 mixture of carbon monoxide (CO) and carbon dioxide (CO₂) upon heating to 0 °C. The stability and conformation of the molecule were also analyzed by theoretical methods.

Óðr

In Norse mythology, Óðr (Old Norse for the "Divine Madness, frantic, furious, vehement, eager", as a noun "mind, feeling" and also "song, poetry"; Orchard (1997) gives "the frenzied one") or Óð, sometimes angliziced as Odr or Od, is a figure associated with the major goddess Freyja. The Prose Edda and Heimskringla, written in the 13th century by Snorri Sturluson, both describe Óðr as Freyja's husband and father of her daughter Hnoss. Heimskringla adds that the couple produced another daughter, Gersemi. A number of theories have been proposed about Óðr, generally that he is somehow a hypostasis of the deity Odin due to their similarities.

Etymology

The Old Norse noun óðr may be the origin of the theonym Óðinn (Anglicized as Odin), and it means "mind", "soul" or "spirit" (so used in stanza 18.1 of the Poetic Edda poem Völuspá). In addition, óðr can also mean "song", "poetry" and "inspiration", and it has connotations of "possession". It is derived from a Proto-Germanic *wōð- or *wōþ- and it is related to Gothic wôds ("raging", "possessed"), Old High German wuot ("fury" "rage, to be insane") and the Anglo-Saxon words wód ("fury", "rabies") and wóð ("song", "cry", "voice", "poetry", "eloquence"). Old Norse derivations include œði "strong excitation, possession".
