2-Chloro-3-[(2-oxo-2H-chromen-6-yl)amino]naphthalene-1,4-dione
In the title compound, C19H10ClNO4, the dihedral angle between the naphtho-quinone and coumarin rings is 48.99 (6)°. In the crystal, mol-ecules are linked by strong N-H⋯O hydrogen bonds into chains with graph-set motif C(6) along [101]. The packing also features π-π stacking inter-actions between naphtho-quinone and coumarin rings [centroid-to-centroid distances = 3.7679 (12) and 3.6180 (13) Å].

In the title compound, C15H16ClNO2S2, the 2H-chromene ring system is nearly planar, with a maximum deviation of 0.023 (2) Å. In the crystal, C-H⋯O hydrogen bonds give R 2 (1)(7) motifs, which generate [100] chains. C-H⋯π and π-π inter-actions between chromene moieties [shortest ring centroid-centroid distance = 3.6199 (13) Å] consolidate the packing.

In the title compound, C(17)H(13)ClO(3), the coumarin and phen-oxy moieties are essentially co-planar, making a dihedral angle of 1.99 (7)°. The phen-oxy moiety is oriented anti-periplanar with respect to the coumarin ring as indicated by the C-C-O-C angle of -179.97 (16)°. In the crystal, the sheet-like packing is stabilized by inter-molecular C-H⋯O and C-H⋯Cl hydrogen bonds.

There are two independent mol-ecules in the asymmetric unit of the title compound, C16H15NO3S2, in which the pyrrolidine rings adopt envelope conformations, with a methyl-ene C atom as the flap. The dihedral angles betweeen the near-planar 2H-chromene ring systems [maximum deviations = 0.0167 (20) and 0.0136 (19) Å] and the pyrrolidine rings (all atoms) are 83.83 (11) and 82.43 (11)°. In the cr...

In the title compound, C(32)H(24)O(8), the mol-ecular structure is disordered over two positions with refined site occupancies of 0.8746 (10) and 0.1254 (10). The mean plane of the three chromeno rings make dihedral angles with each other of 65.12 (4), 62.91 (4) and 59.70 (4)° in the major occupancy component and 59.1 (3), 66.1 (3) and 58.8 (3)° in the minor component. Intra-molecular O-H⋯O hyd...
