1-[3-(Naphthalen-1-yl)phen­yl]naphthal­ene

The title compound, C₂₆H₁₈, consists of a benzene ring with meta-substituted 1-naphthalene substituents, which are essentially planar (r.m.s. deviation = 0.039 and 0.027 Å). The conformation is mixed syn/anti, with equivalent torsion angles about the benzene-naphthalene bonds of 121.46 (11) and 51.58 (14)°.

2-[3-(Naphthalen-2-yl)phen­yl]naph­thal­ene

The title compound, C₂₆H₁₈, consists of a benzene ring with meta-substituted 2-naphthalene substituents, which are essentially planar [r.m.s. deviations = 0.022 (1) and 0.003 (1) Å]. The conformation is syn, with equivalent torsion angles about the benzene-naphthalene bonds of -36.04 (13) and +34.14 (13)°. The mol­ecule has quasi-C_s mol­ecular symmetry.
