(7-Chloro-2-oxo-2H-chromen-4-yl)methyl diethylcarbamodithioate
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, C13H12Cl N O2S2, the 2H-chromene ring system is almost planar, with a maximum deviation of 0.005 (2) Å. The packing features C-H⋯S hydrogen bonds and π-π inter-actions between fused benzene rings of chromene [shortest centroid-centroid distances = 3.6553 (13) and 3.5551 (13) Å].
متن کاملCrystal structure of 7-[(2E)-2-benzylidene-3-oxobutoxy]-4-methyl-2H-chromen-2-one
Two independent mol-ecules (A and B) comprise the asymmetric unit of the title compound, C21H18O4. There are significant conformational differences between the mol-ecules relating in particular to the relative orientation of the 3-oxo-2-(phenyl-methyl-idene)but-oxy substituent with respect to the superimposable chromen-2-one residues. To a first approximation, the substituents are mirror images...
متن کامل4-Benzyl-7-chloro-2H-1,4-benzoxazin-3(4H)-one
In the title compound, C(15)H(12)ClNO(2), the two benzene rings are nearly perpendicular to each other [dihedral angle = 89.99 (13)°]. The O atom of the six-membered heterocyclic ring is disordered over two sites in a ratio of 0.46 (4):0.54 (4) and is displaced from the mean plane formed by other five atoms, resulting an envelope conformation of the six-membered hetercycle ring.
