6,8-Di-tert-butyl-3-(4-nitro-phen-yl)-2H-chromen-2-one.

ABSTRACT: The title compound, C(23)H(25)NO(4), was synthesized by the reaction of 2-(4-nitro-phen-yl)acetonitrile and 3,5-di-tert-butyl-2-hydroxy-benzaldehyde. The dihedral angle formed by the benzene ring and the mean plane through the benzopyran-one ring system is 35.57?(5)°. The nitro group is almost coplanar with the attached benzene ring [dihedral angle = 5.19?(15)°]. The crystal packing is stabilized by an inter-molecular C-H?O hydrogen-bond inter-action.

4-Bromo-methyl-6-tert-butyl-2H-chromen-2-one.

Project description:In the crystal structure of the title compound, C14H15BrO2, weak C-H⋯O inter-actions link the mol-ecules into zigzag chains extending along the c-axis direction. These chains are further assembled into (100) layers via π-π stacking inter-actions between inversion-related chromenone fragments [inter-planar distance = 3.376 (2) Å].

2-Oxo-2H-chromen-4-yl 4-tert-butyl-benzoate.

Project description:In the title mol-ecule, C(20)H(18)O(4), the three methyl groups of the tert-butyl substituent show rotational disorder. Each methyl group is split over three positions, with refined site-occupation factors of 0.711?(4), 0.146?(3) and 0.144?(4). The benzene ring of the benzoate group is oriented at a dihedral angle of 60.70?(7)° with respect to the planar chromene ring [maximum deviation = 0.046?(2)?Å]. The crystal structure features centrosymmetric R(2) (2)(8) dimers formed via C-H?O inter-actions, and these dimeric aggregates are connected by C-H?? inter-actions.

3-Hydroxy-meth-yl-6,8-dimeth-oxy-2H-chromen-2-one.

Project description:The asymmetric unit of the title compound, C(12)H(12)O(5), contains four independent mol-ecules. In the crystal structure, inter-molecular O-H?O hydrogen bonds link the mol-ecules into one-dimensional infinite chains. They are arranged in a nearly parallel fashion along the b axis and stabilized by ?-? inter-actions [3.443?(2)?Å].

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⋯π inter-actions, with groups of four mol-ecules stacked along the c axis.

Project description:In the title compound, C17H13Cl2NO2, the H atom of the -OH group is transferred to the N atom of the imine, forming a zwitterion. Thus, there is a intra-molecular O?H-N, rather than O-H?N, hydrogen bond, which forms a six-membered ring.

Crystal structure of 2-(4-tert-butyl-phen-yl)-3-hydroxy-4H-chromen-4-one.

Project description:Yellow-green fluorescent crystals of the title compound, C19H18O3, were obtained by the reaction of hy-droxy-aceto-phenone and 4-tert-butyl-benzaldehyde with hydrogen peroxide as oxidant. The plane of the benzene ring is slightly twisted to the mean plane of the 4H-chromene-4-one moiety (r.m.s. deviation = 0.0191 Å) by 10.53 (8)°. In the crystal, mol-ecules are linked by pairs of O-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(10) ring motif. The dimers are linked via C-H⋯π inter-actions, forming sheets parallel to (10-1).

Project description:In the title compound, C17H13NO5, the coumarin ring system is essentially planar (r.m.s. deviation = 0.008?Å). The nitro-phenyl ring makes a dihedral angle of 25.27?(9)° with the coumarin ring plane. The nitro group is almost coplanar with the phenyl ring to which it is attached, making a dihedral angle of 4.3?(3)°. The eth-oxy group is inclined to the coumarin ring plane by 4.1?(2)°. Electron delocalization was found at the short bridging C-C bond with a bond length of 1.354?(2)?Å. In the crystal, mol-ecules are linked via C-H?O hydrogen bonds, forming sheets in the bc plane. The sheets are linked via ?-? stacking [centroid-centroid distances = 3.5688?(13) and 3.7514?(13)?Å], forming a three-dimensional structure.

Project description:In the title compound, C21H15Cl2NO2, the H atom of the -OH group is transferred to the N atom of the imine, forming a zwitterion.

[centroid-centroid distances = 3.744?(3) and 3.780?(3)?Å], C-Cl?? [Cl?centroid = 3.261?(3)?Å], C-H?? and C-H?O inter-actions.
