10,11-Dihydro-diindeno[1,2-b:2',1'-d]thio-phene.

ABSTRACT: The title compound, C(18)H(12)S, comprises five fused rings forming an essentially planar mol-ecule, with a total puckering amplitude (Q) of 0.032?Å and a maximum deviation from the mean plane of 0.014?(4)?Å for the C atoms of the methyl-ene groups. A crystallographic mirror plane orthogonal to the mol-ecular plane passes through the S atom and the midpoint of the opposite C-C bond within the central five-membered ring. The mol-ecules lie in layers, forming edge-to-face C-H?? inter-actions, with a separation of 2.66?Å between one H atom of the methyl-ene group and the centroid of an adjacent indene ring.
