Abstract: The dihedral angle between the least-squares planes through the C atoms of the six-membered rings of the title indene dimer, C₁₈H₁₆, is 85.53  (11)°. The five-membered ring in the indene moiety is nearly planar [torsion angles: -0.4  (3), 0.1  (4), 0.3  (4), -0.6  (3) and 0.6  (3)°], whereas the other five-membered ring deviates markedly from planarity [torsion angles: -15.3  (4), 14.3  (4), -7.8  (4), -1.5  (4), 10.7  (4)°]. The central C-C bond length is 1.488  (4)  Å.
