Adamantane (tricyclo[188.8.131.52,7]decane) is a colourless, crystalline compound with a camphor-like odour. With a formula C10H16, it is a cycloalkane and also the simplest diamondoid. Adamantane was discovered in petroleum in 1933. Its name derived from the Greek adamantinos (relating to steel or diamond), due to its diamond-like structure. Adamantane is the most stable isomer of C10H16.
In dye lasers, adamantane may be used to extend the life of the gain medium; it cannot be photoionised under atmosphere because its absorption bands lie in the vacuum-ultraviolet region of the spectrum. Photoionization energies have been determined recently for adamantane as well as for several bigger diamondoids.
Due to its stability, specific steric properties and conformational rigidity, the 1-adamantyl group is a (bulky) substituent in organic and organometallic chemistry. Some of the first persistent carbenes featured adamantyl substituents.
