چکیده
In the title mol-ecule, C(17)H(11)F(3)O, 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.

In the title compound, C(14)H(10)O(2), the five-membered ring of the inden-1-one residue is almost planar (r.m.s. deviation = 0.035 Å). A twist about the single bond linking the two residues is evident [C-C-C-C torsion angle = -13.2 (5)°]. The three-dimensional architecture is stabilized by C-H⋯O (involving the trifurcated carbonyl O atom), C-H⋯π and π-π inter-actions [between the five- and six...
