Adamantane (formally tricyclo[3.3.1.13,7]decane) is an exquisitely symmetrical hydrocarbon that was originally isolated from petroleum in 1933 by the Czech researchers S. Landa and V. Machacek. Its synthesis was first reported by Vladimir Prelog in 1941. It’s the simplest diamondoid compound and is nice to look at, but it has few practical applications.
