Abstract

In the title mol-ecule, C ₁₇H ₁₁F ₃O, the indan ring system and the trifluoro-methyl-substituted benzene ring are approximately individually planar and form a dihedral angle of 1.81 (5)° with each other. In the crystal, mol-ecules are linked by pairs of weak bifurcated (C - H) ₂⋯O hydrogen bonds to form centrosymmetric dimers, generating R ₂ ¹(6) and R ₂ ²(10) ring motifs. These dimers are connected by further weak C - H⋯O hydrogen bonds into one-dimensional chains along the b axis. Weak C - H⋯π inter-actions are also present.
