6,7-Dimethoxy-1,4-anthraquinone
The mol-ecule of the title compound, C(16)H(12)O(4), is almost planar; the two meth-oxy groups are slightly out of the plane of the anthraquinone ring system, with C-C-O-C torsion angles of -6.25 (19) and -10.22 (19)°. In the crystal structure, the mol-ecules adopt a herringbone arrangement and form face-to-face slipped anti-parallel π-π stacking inter-actions along the b axis, with an inter-pl...
متن کامل2,6-Dimethoxy-9,10-anthraquinone
The title compound, C(16)H(12)O(4), crystallizes with two half-mol-ecules in the asymmetric unit, each of which is completed by a crystallographic inversion center. The two crystallographically independent mol-ecules have almost the same geometry and are almost planar [maximum deviations = 0.018 (3) and 0.049 (3) Å]. They adopt a conformation in which the C(meth-yl)-O bonds are directed along t...
متن کامل1-Dimethylamino-9,10-anthraquinone
In the crystal structure of the title compound, C(16)H(13)NO(2), adjacent mol-ecules are linked through C-H⋯π and π-π [centroid-centroid distances = 3.844 (2) Å] contacts. The anthracene ring system and dimethyl-amino group are oriented at a dihedral angle of 38.4 (1)°. In the crystal, the mean planes of adjacent anthracene units are inclined at angles of 59.3 (1), 75.7 (1) and 76.0 (1)°.
متن کامل1-(2-Methoxyanilino)anthraquinone
In the title compound, C(21)H(15)NO(3), the dihedral angle formed between the aromatic ring systems is 71.50 (3)°. The meth-oxy group is coplanar with the benzene ring to which it is connected, the C-O-C-C torsion angle being 6.37 (17)°. The observed conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond, generating an S(6) ring.
متن کامل2-(Dimethylamino)anthraquinone
The mol-ecule of the title compound, C(16)H(13)NO(2), is almost planar, with a maximum deviation of 0.013 (2) Å from the best plane; the dihedral angle between the two aromatic rings is 1.06 (1)°. In the crystal, mol-ecules are linked through weak intra-molecular C-H⋯O inter-actions, forming chains running parallel to [10].
