Nitrous oxide transfer of nitrous oxide from bulk cylinders to smaller, more transportable E-type, 1590 liter-capacity tanks, is legal when the intended use of the gas is for medical anaesthesia. Nitrous oxide Nitrous oxide, commonly known as laughing gas or nitrous, is a chemical compound, an oxide of nitrogen with the formula . At room temperature, it is a colourless non-flammable gas, with a slight metallic scent and taste. At elevated temperatures, nitrous oxide is a powerful oxidizer similar to molecular oxygen. It is soluble in water. Nitrous oxide has significant medical uses, especially in surgery and dentistry, for its anaesthetic and
Dihydrogen complex variety of related complexes such as Cr(H)(CO) and [Fe(H)(H)(dppe)]. Kubas et al.'s findings also led to a reevaluation of previously described compounds. For example, the complex "RuH(PPh)" described in 1968 was reformulated as a dihydrogen complex. Dihydrogen complex Dihydrogen complexes are coordination complexes containing intact H as a ligand. The prototypical complex is W(CO)(PCy)(H). This class of compounds represent intermediates in metal-catalyzed reactions involving hydrogen. Hundreds of dihydrogen complexes have been reported. Most examples are cationic transition metals complexes with octahedral geometry. Upon complexation, the H−H bond is extended to 0.81–0.82 Å as indicated by neutron diffraction, about a 10%
