3,6-Dibromo-7-ethyl-amino-4-methyl-2H-chromen-2-one.

ABSTRACT: In title compound, C(12)H(11)Br(2)NO(2), the coumarin ring system is almost planar, the two rings being inclined to one another by 1.40?(15)°. There are two short intra-molecular inter-actions (N-H?Br and C-H?Br) involving the Br atoms. In the crystal, mol-ecules stack along the a-axis direction via ?-? inter-actions; the centroid-centroid distances vary from 3.6484?(19) to 3.7942?(19)?Å.

In title compound, C(12)H(11)Br(2)NO(2), the coumarin ring system is almost planar, the two rings being inclined to one another by 1.40 (15)°. There are two short intra-molecular inter-actions (N-H⋯Br and C-H⋯Br) involving the Br atoms. In the crystal, mol-ecules stack along the a-axis direction via π-π inter-actions; the centroid-centroid distances vary from 3.6484 (19) to 3.7942 (19) Å. ...[more]

4-[(4-Methyl-benz-yl)amino]-3-[(4-methyl-benz-yl)imino-meth-yl]-2H-chromen-2-one.

Project description:The title compound, C(26)H(24)N(2)O(2), was prepared from the reaction of 4-chloro-3-formyl-coumarin with p-methyl-benzyl-amine. Even though there are no strong and specific inter-actions in the crystal structure, the translationally related mol-ecules form chains along the b axis. The coumarin moieties are stacked through ?-? inter-actions [centroid-centroid distance = 3.5275?(7)?Å], forming layers perpendicular to the stacking direction.

7-[(3,5-Di-tert-butyl-2-hy-droxy-benzyl-idene)amino]-4-methyl-2H-chromen-2-one.

Project description:The title compound, C(25)H(29)NO(3), is a Schiff base derivative of coumarin 120. There are two structurally similar but crystallographically independent mol-ecules in the asymmetric unit. Both mol-ecules exist in E configurations with respect to the C=N double bonds. The dihedral angles between the coumarin and 3,5-di-tert-butyl-2-hy-droxy-benzyl-idene ring planes are 4.62?(7) and 14.62?(7)° for the two mol-ecules. Intra-molecular O-H?N hydrogen bonding involving the O-H groups and the azomethine N atoms generate S(6) rings. In the crystal structure, independent mol-ecules are linked by C-H?? inter-actions, with groups of four mol-ecules stacked along the c axis.
