Arsenicin A is a naturally occurring organoarsenic compound. It was first isolated from the New Caledonian marine sponge Echinochalina bargibanti.[1] The compound was characterized by computational and spectroscopic[2][3] techniques and found to possess a cage-like structure similar to adamantane in which four carbon atoms are replaced by arsenic atoms and another three are replaced by oxygen atoms. It is the first polyarsenic compound ever found in nature.[1] Subsequently, the proposed structure was prepared in the laboratory by organic synthesis and the structure was confirmed by x-ray crystallography.[4]
