Wampenite, C18H16, is a new organic mineral from the fossil wood (conifer) locality at Wampen, Fichtelgebirge, Bavaria, Germany. It is monoclinic, space group P2 1/a, with a = 6.7331(19), b = 8.689(3), c = 23.709(7) Å, β = 90.118(6)°, V = 1387.0(7) Å3 and Z = 4. Its structure was determined by single-crystal X-ray diffraction, which revealed that the molecular structure comprises an aromatic phenanthrene moiety with an axial methyl group at one end and a disordered propen-2-yl (methylvinyl) terminal group at the other. High resolution mass spectrometry (HRMS) confirmed the molecular formula C18 H16 and the IR spectrum is consistent with the molecular structure found.
