(2,7-Dimethoxynaphthalen-1-yl)(4-phenoxyphenyl)methanone

In the title molecule, C25H20O4, the naphthalene and phenoxy groups are oriented nearly perpendicular with respect to the benzene ring of the benzoyl group, with dihedral angles of 89.61 (5) and 86.13 (6)°, respectively. The crystal structure features C—H⋯O and C—H⋯π interactions.

As a part of our ongoing studies on the molecular structures of these kinds of homologous molecules, the X-ray crystal structure of the title compound, (2,7-dimethoxynaphthalen-1-yl)(4-phenoxyphenyl)methanone, 2,7-dimethoxynaphthalene bearing phenoxybenzoyl group at the 1-position, is discussed in this article.
The molecular structure of the title compound is displayed in Fig 1. The dihedral angle between the best planes of the benzene ring of the internal benzoyl moiety and the naphthalene ring is 89.61 (5) °. In addition, the dihedral angle between the benzene rings of 4-phenoxybenzoyl moiety is 86.13 (6) °.
Moreover, the molecules are alternately aligned along c axis (Fig. 3).

Refinement
All H atoms were found in a difference map and were subsequently refined as riding atoms, with C-H = 0.95 (aromatic) and 0.98 (methyl) Å with U ĩso (H) = 1.2 U eq (C).     The alignment of the molecules along the c axis.

Computing details
(2,7-Dimethoxynaphthalen-1-yl)(4-phenoxyphenyl)methanone Refinement. Refinement of F 2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F 2 , conventional R-factors R are based on F, with F set to zero for negative F 2 . The threshold expression of F 2 > σ(F 2 ) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F 2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
