title: 1,2-Di-hydro-spiro-[carbazole-3(4H),2'-[1,3]dioxolane].
abstract: In the title compound, C(14)H(15)NO(2), 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 mol-ecules form edge-to-face inter-actions in which the NH group is directed towards an adjacent carbazole unit, with a shortest H⋯C contact of 2.72 Å. These inter-actions arrange the mol-ecules into one-dimensional herringbone-type motifs, which pack so that the methyl-ene groups of the dioxolane ring lie over the face of a neighbouring carbazole unit with a shortest H⋯C contact of 2.85 Å.
