title: 5-Methyl-phenanthro[2,3-b]thio-phene.
abstract: The title compound, C(17)H(12)S, which crystallises with two molecules in the asymmetric unit, features four fused rings forming an essentially planar mol-ecule, with maximum deviations from the mean plane of 0.078 (2) and 0.080 (2) Å for C atoms of the thio-phene and phenanthrene groups in both the mol-ecules. The crystal packing features weak C-H⋯π inter-actions.
