Crystal structure of 3-(4-meth-oxy-phen-yl)-2,3-di-hydro-1H-naphtho-[2,1-b]pyran-1-one.

ABSTRACT: In the title compound, C20H16O3, the hydro-pyran ring adopts a distorted half-chair conformation with the methine C atom and the ring O atom displaced by -0.554?(2) and 0.158?(1)?Å, respectively, from the plane of the other four atoms (r.m.s. deviation = 0.020?Å). Its mean plane (all atoms) is inclined to the naphthalene ring system at a dihedral angle of 11.67?(1)°. The dihedral angle between the napthalene ring system and the phenyl ring is 71.84?(1)°. In the crystal, no diectional inter-actions beyond van der Waals contacts could be identified.

6-(4-Meth-oxy-phen-yl)naphtho[2,3-b][1]benzothio-phene.

Project description:The asymmetric unit of the title compound, C23H16OS, contains two independent mol-ecules with opposite orientations of the meth-oxy groups bonded to the benzene rings.

Project description:The title mol-ecule, C15H12ClNO, features a di-hydro-quinolin-4(1H)-one moiety attached to a chloro-benzene ring.
