Crystal structure of dimethyl 1-oxo-2,4-di-phenyl-1,2-dihydronaphthalene-2,3-di-carboxyl-ate.

ABSTRACT: In the title compound, C26H20O5, a 1,2-di-hydro-naphthalene derivative, the cyclo-hexa-1,3-diene ring of the 1,2-di-hydro-naphthalene ring system adopts a half-chair conformation. The mean plane of the 1,2-di-hydro-napthalene ring system makes dihedral angles of 86.23?(6) and 64.80?(7)° with two phenyl rings. The carbonyl O atom attached to the di-hydro-naphthalene ring system deviates from the mean plane of the 1,2-di-hydro-naphthalene ring system by 0.618?(1)?Å. In the crystal, the mol-ecules are linked into layers parallel to the bc plane via two kinds of C-H?O inter-actions, one of which forms a C(10) chain motif running along the c-axis direction and the other forms an R22(6) ring motif. Adjacent layers are further connected by C-H?? and offset ?-? inter-actions [centroid-centroid distance = 3.6318?(9)?Å].
