7-Hydroxy-4-methyl-8-(3-methylbenzoyl)-2H-chromen-2-one ethanol monosolvate
In the title compound, C(18)H(14)O(4)·C(2)H(6)O, the coumarin ring system is approximately planar with a maximum deviation of 0.037 (3) Å and is nearly perpendicular to the benzene ring, making a dihedral angle of 86.55 (9)°. In the crystal, mol-ecules are linked by classical O-H⋯O hydrogen bonds and weak C-H⋯O inter-actions.

In the title compound, C(12)H(11)IO(4), the C and O atoms of both meth-oxy groups lie very close to the mean plane of the six C atoms of the benzene ring. The O and C atoms of the group lying closest to the I atom are 0.012 (3) and 0.022 (4) Å, respectively, out of the mean plane. For the other meth-oxy group, the corresponding distances are 0.020 (3) and 0.078 (4) Å. In the crystal, there are ...
متن کامل3,6,8-Tribromo-7-ethylamino-4-methyl-2H-chromen-2-one
In the title mol-ecule, C(12)H(10)Br(3)NO(2), the 2H-chromen ring is essentially planar (r.m.s. deviation = 0.022 Å) with the ethyl-amino group oriented at 13.9 (5)° with respect to the ring. The mol-ecular structure is stabilized by intra-molecular N-H⋯Br and C-H⋯Br interactions.
متن کامل3,6-Dibromo-7-ethylamino-4-methyl-2H-chromen-2-one
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.
