1-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)°.

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.

In the title compound, C(19)H(17)NO(2), the piperidine ring adopts a chair conformation. The mean planes of the piperidine ring and the anthracene ring system are inclined at a dihedral angle of 38.7 (1)°. In the crystal, adjacent mol-ecules are linked through C-H⋯π and π-π [centroid-centroid distance = 3.782 (1) Å] inter-actions, forming a layer parallel to the bc plane.

It is a unique human ability to regulate negative thoughts and feelings. Two well-investigated emotion-regulation strategies (ERSs), cognitive reappraisal and expressive suppression, are associated with overlapping prefrontal neural correlates, but differ temporally during the emotion-generation process. Although functional imaging studies have mainly investigated these ERS as a reaction to an ...

The non-H atoms of the title compound, C(16)H(12)O(3), lie approximately in a common plane (r.m.s. deviation = 0.032 Å). The methyl C atom is forced away from the carbonyl O atom which can be seen by the widened C(fused ring)-C(benzene)-C(meth-yl) angle of 125.8 (2)°.
