A spiro-linked pyrene-naphthoquinone.
The title molecule, 2'-pyrenylspiro[2, 3-dihydro-1H-cyclopenta[b]naphthalene-2,5'-1',3'-dioxane]-4,9-dione, C(32)H(22)O(4), contains an electron-donating pyrene group spiro-linked to an electron-accepting naphthoquinone. The molecules are V-shaped in profile and stack to form columns along b with alternating, approximately coplanar, pyrene and naphthoquinone fragments. Intermolecular contacts within a column are consistent with some degree of pi contact and possible long-range delocalization. Individual columns form a herringbone pattern when the crystal is viewed along b.
