title: rac-(Z)-Methyl 1-benzyl-3-[(3-hy-droxy-quinuclidin-2-yl-idene)meth-yl]-1H-indole-6-carboxyl-ate.
abstract: In the title compound, C(25)H(26)N(2)O(3), the double bond connecting the aza-bicyclic and indole units has Z geometry. The compound was obtained as a racemate, and since the crystal is centrosymmetric it contains equal amounts of the S and R enanti-omers. However, the structure is disordered such that the asymmetric unit contains both enanti-omers in unequal amounts [refined occupancies 0.904 (2) and 0.096 (2)]. The dihedral angle between the benzene ring of the benzyl group and the mean plane of the indole ring is 76.07 (3) °. In the crystal, mol-ecules are linked by O-H⋯O(carbon-yl) hydrogen bonds into chains propagating in [110].
