RESUMO
In the title compound, C15H16ClNO2S2, the 2H-chromene ring system is nearly planar, with a maximum deviation of 0.023â (2)â Å. In the crystal, C-Hâ¯O hydrogen bonds give R 2 (1)(7) motifs, which generate [100] chains. C-Hâ¯π and π-π inter-actions between chromene moieties [shortest ring centroid-centroid distance = 3.6199â (13)â Å] consolidate the packing.
RESUMO
In the title compound, C16H17NO3S2, the dihedral angles between the O/C/C/S group and the 2H-chromene ring system and the thio-carbamate group are 14.46â (9) and 83.30â (9)°, respectively. The bond-angle sum at the N atom is 360.0°. One of the methyl C atoms lies above the thio-carbamate plane and one lies below it [deviations = 1.264â (3) and -1.147â (3)â Å, respectively]. In the crystal, inversion dimers linked by pairs of C-Hâ¯O hydrogen bonds generate R 2 (2)(10) loops. Weak aromatic π-π stacking inter-actions [shortest centroid-centroid distance = 3.8138â (11)â Å] are also observed.
RESUMO
In the title compound, C(17)H(16)O(6), the two benzene rings form a dihedral angle of 54.95â (10)°. Only weak inter-molecular inter-actions are present in the crystal structure, viz. C-Hâ¯O hydrogen bonds and C-Hâ¯π inter-actions involving one of the benzene rings.
RESUMO
In the title compound, C(16)H(12)O(4), the chromene ring system is almost planar [maximum deviation = 0.026â (1)â Å] and makes dihedral angles of 1.24â (9) and 26.5â (2)° with the fused benzene ring and the plane of the ethyl carboxyl-ate group, respectively.
RESUMO
In the title compound, C17H17N O4S, the quinoline ring system is nearly planar, with a maximum deviation of 0.0496â (16)â Å. A weak intra-molecular C-Hâ¯O inter-action is observed. In the crystal, C-Hâ¯O, S-Hâ¯N and π-π stacking inter-actions between the fused benzene ring of quinoline and the pyridine moieties [shortest centroid-centroid distance = 3.6754â (11)â Å] are observed. Inversion-related weak C-Hâ¯O inter-molecular inter-actions diagonally along [010], with R 2 (2)(10) ring motifs, and S-Hâ¯N inter-molecular inter-actions diagonally along [100], with R 2 (2)(8) ring motifs, are present, forming a three-dimensional network structure. No classical hydrogen bonds are observed.
RESUMO
In the title compound, C17H19NO2S2, the 2H-chromene ring system is nearly planar, with a maximum deviation of 0.0383â (28)â Å, and the piperidine ring adopts a chair conformation. The 2H-chromene ring makes dihedral angles of 32.89â (16) and 67.33â (8)°, respectively, with the mean planes of the piperidine ring and the carbodi-thio-ate group. In the crystal, C-Hâ¯O and weak C-Hâ¯S hydrogen bonds link the mol-ecules into chains along [001]. The crystal structure also features C-Hâ¯π and π-π inter-actions, with a centroid-centroid distance of 3.7097â (17)â Å.
