(E)-2-[4-(Trifluoro-meth-yl)benzyl-idene]-2,3-dihydro-1H-inden-1-one.


ABSTRACT: 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?? inter-actions are also present.
