Diatomic carbon (systematically named dicarbon and 1λ2,2λ2-ethene), is a green, gaseous inorganic chemical with the chemical formula C=C (also written [C 2] or C 2). It is kinetically unstable at ambient temperature and pressure, being removed through autopolymerisation.

Orthocarbonic acid, carbon hydroxide, methanetetrol is the name given to a hypothetical compound with the chemical formula H4CO4 or C (OH)4. Its molecular structure consists of a single carbon atom bonded to four hydroxyl groups. It would be therefore a fourfold alcohol.

2019年11月15日 · As the dicarbon anion C \ ( {}_ {2}^ {-}\) is stable, photoelectron spectroscopy may be used to probe the reactive C \ ( {}_ {2}\) neutral molecule 24, 25.

The dicarbon molecule (C 2) is found in flames, comets, stars, and the diffuse interstellar medium. In comets, it is responsible for the green color of the coma, but it is not found in the tail. It has long been held to photodissociate in sunlight with a lifetime precluding observation in the tail, but the mechanism was not known.

In spite of its apparent simplicity, the dicarbon molecule has a bonding structure which is matter of debate. Here the authors measure high-resolution spectra of the C 2 anion by photoelectron imaging, revealing a bonding configuration dominated by a double π …

2020年11月30日 · Here we have prepared and structurally characterized diatomic C 2 as a monoligated complex L→C 2 using a bulky phosphine ligand bearing two imidazolidin-2-iminato groups (L is (NHC R =N) 2 (CH 3)P,...

The dicarbon molecule is of great interest to quantum chemists not only because it plays an important role in some chemical reaction mechanisms and is present in the interstellar matter, but also because it is challenging from the theoretical point of view.

Dicarbon monoxide (C2O) is a molecule that contains two carbon atoms and one oxygen atom. It is a linear molecule that, because of its simplicity, is of interest in a variety of areas. It is, however, so extremely reactive that it is not encountered in everyday life. It is classified as a carbene, cumulene and an oxocarbon. [1]

The C-C bond in dicarbon involves all va- lence electrons from each carbon, i.e. 8, and they are around each atom's helium core. The diamagnetism of this molecule reveals that all its bonded ...
