1,2-Dihydrospiro[carbazole-3(4H),2'-[1,3]dioxolane]

J. V. Bjerrum, T. Ulven and A. D. Bond

Abstract: In the title compound, C₁₄H₁₅NO₂, the hydrogenated six-membered ring of the carbazole unit adopts a half-chair conformation and the dioxolane ring points to one side of the carbazole plane. Neighbouring molecules form edge-to-face interactions in which the NH group is directed towards an adjacent carbazole unit, with a shortest HC contact of 2.72 Å. These interactions arrange the molecules into one-dimensional herringbone-type motifs, which pack so that the methylene groups of the dioxolane ring lie over the face of a neighbouring carbazole unit with a shortest HC contact of 2.85 Å.
