2-Chloro-3-[(2-oxo-2H-chromen-6-yl)amino]-naphthalene-1,4-dione.

ABSTRACT: 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].

2,3-Bis(2-chloro-benz-yl)naphthalene-1,4-dione.

Project description:The title disubstituted naphthalene-1,4-dione, C(24)H(16)Cl(2)O(2), has the two chloro-benzyl substituents related by a non-crystallographic twofold rotation axis, generating a chiral conformation; both enantiomers are present. The two chlorobenzene rings are nearly perpendicular to the fused ring system, making angles of 88.8 (1) and 77.5 (1)° with it.

(7-Chloro-2-oxo-2H-chromen-4-yl)methyl piperidine-1-carbodithio-ate.

Project description:In the title compound, C(16)H(16)ClNO(2)S(2), the piperidine ring is in a chair conformation. In the coumarin ring system, the dihedral angle between the benzene and pyran rings is 3.5 (1)°. In the crystal, a weak C-H⋯O hydrogen bond links mol-ecules into chains along [001]. In addition, π-π stacking inter-actions are present involving the benzene and pyran rings, with a centroid-to-centroid distance of 3.712 (2) Å. The crystal studied is a nonmerohedral twin with refined components 0.221 (1) and 0.779 (1).

2-Oxo-2H-chromen-4-yl propionate.

Project description:In the title compound, C12H10O4, the atoms of the 2-oxo-2H-chromene ring system and the non-H atoms of the 4-substituent all lie on a crystallographic mirror plane. The mol-ecular structure exhibits an intra-molecular C-H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, mol-ecules form R 3 (2)(12) trimeric units via C-H⋯O inter-actions which propagate into layers parallel to the ac plane. These layers are linked by weak C-H⋯O inter-actions along the [010] direction, generating a three-dimensional network.

(7-Chloro-2-oxo-2H-chromen-4-yl)methyl di-ethyl-carbamodi-thio-ate.

Project description: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.

(7-Chloro-2-oxo-2H-chromen-4-yl)methyl pyrrolidine-1-carbodi-thio-ate.

Project description:In the title compound, C15H14ClNO2S2, the 2H-chromene ring system is essentially planar, with a maximum deviation of 0.0133 (10) Å. Three C atoms and their attached H atoms of the pyrrolidine ring are disordered [occupany ratio 0.874 (7):0.126 (7)] with both disorder components adopting a twisted conformation. The dihedral angle between the 2H-chromene ring system and the major occupancy component of the pyrrolidine ring is 89.45 (7)°. In the crystal, inversion dimers linked by pairs of C-H⋯S and C-H⋯O inter-actions generate R (2) 2(24) and R (2) 2(10) loops, respectively. Further C-H⋯O hydrogen bonds link the dimers into [100] chains. C-H⋯π inter-actions also occur and there is very weak π-π stacking [inter-planar spacing = 3.650 (5) Å; centroid-centroid distance = 4.095 (7) Å] between inversion-related chloro-benzene rings.

Crystal structure of (tert-butyl-carbamo-yl)(4-chloro-2-oxo-2H-chromen-3-yl)methyl acetate.

Project description:In the title compound, C17H18ClNO5, which was synthesized by reacting 4-chloro-3-formyl-coumarin, acetic acid and tert-butyl isocyanide, the acetamido side chain is convoluted with ring-to-side chain C-C-C-C, C-C-C-N and C-C-N-C torsion angles of -123.30 (14), -135.73 (12) and 176.10 (12)°, respectively. In the crystal, N-H⋯O and weak C-H⋯O hydrogen bonds are present, which together with π-π coumarin-ring inter-actions [ring centroid separations = 3.4582 (8) and 3.6421 (9) Å], give rise to a layered structure lying parallel to (001).

Project description:The phenyl ring in title mol-ecule, C(16)H(11)NO(3), forms a dihedral angle of 7.69 (6)° with the fused ring system. The observed conformation is stabilized by intra-molecular N-H⋯O and C-H⋯O inter-actions. In the crystal, supra-molecular chains are formed along the b axis which are mediated by π-π inter-actions [centroid-centroid distance = 3.614 (2) Å].

Project description:The mol-ecular structure of the title compound, C(16)H(11)BrN(2)O(4)S, is very similar to that of the previously reported fluoro analogue [al-Rashida et al. (2010 ▶). Acta Cryst.
