Natural crystalline anthracene, a.k.a. tricyclo[8.4.0.03,8]tetradeca-1,3,5,7,9,11,13-heptaene

The aromatic hydrocarbon compound C14H10 is known with two isomers: anthracene and phenanthrene. The latter was described as the mineral ravatite (IMA 1992-019) from a burning coal seam near Ravat, Tajikistan (Nasdala and Pekov, 1993).

The mineral kratochvilite, C13H10 (fluorene), is very similar in visual appearance and chemical composition. It is originally described from the burning dumps of the mines Max and Schoeller at Libušin near Kladno, Czech Republic (Rost, 1937).
