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).
