(2E)-2-Benzyl-idene-5,6-dimethoxy-indan-1-one.

ABSTRACT: The mol-ecular structure of the title compound, C(18)H(16)O(3), is roughly planar; the maximum deviation of the indanone ring system is 0.027?(1)?Å and it makes a dihedral angle of 2.69?(3)° with the phenyl ring. The torsion angles between the two meth-oxy groups and the -indanone ring are -14.67?(11) and -1.11?(12)°. In the crystal, mol-ecules are connected into a ribbon along the a axis via weak inter-molecular C-H?O hydrogen bonds. Weak inter-molecular C-H?? and ?-? [centroid-centroid distance = 3.7086?(6)?Å] inter-actions are also observed.

The mol-ecular structure of the title compound, C(18)H(16)O(3), is roughly planar; the maximum deviation of the indanone ring system is 0.027 (1) Å and it makes a dihedral angle of 2.69 (3)° with the phenyl ring. The torsion angles between the two meth-oxy groups and the -indanone ring are -14.67 (11) and -1.11 (12)°. In the crystal, mol-ecules are connected into a ribbon along the a axis via weak inter-molecular C-H⋯O hydrogen bonds. Weak inter-molecular C-H⋯π and π-π [centroid-centroid distanc  ...[more]
