Ethyl anthracene-9-carboxylate
In the title compound, C(17)H(14)O(2), the COO group and the anthracene fragment form a dihedral angle of 76.00 (19)°. The torsion angle around the O-Csp(3) bond of the ester group is 108.52 (18)°. The crystal structure is stabilized by C-H⋯O inter-actions and edge-to-face arene inter-actions with C-H⋯(ring centroid) distances in the range 2.75-2.84 Å.
متن کامل9-(Dimethoxymethyl)anthracene
In the title compound, C(17)H(16)O(2), a dimethyl acetal of 9-anthraldehyde, the anthracene skeleton is planar and the two meth-oxy groups attached to the C atom at position 9 of the aromatic ring system are located above and below the ring system.
متن کامل9-(4-Methoxyphenyl)anthracene
In the title compound, C21H16O, the dihedral angle between the anthracene ring system and the benzene ring is 74.3 (5)°. The anthracene ring system is essentially planar (r.m.s. deviation = 0.0257 Å) and the meth-oxy group lies in the plane of the benzene ring [C1-O1-C2-C7 torsion angle = 0.5 (2)°]. The crystal structure features π-π [centroid-centroid distance = 3.9487 (12) Å] and C-H⋯π inter-...
متن کامل(E)-2-{Ethyl[4-(4-nitrophenyldiazenyl)phenyl]amino}ethyl anthracene-9-carboxylate
The crystal structure of the title compound, C(31)H(26)N(4)O(4), displays a trans conformation for the nitro-phenyl-diazenyl portion of the mol-ecule. Packing diagrams indicate that weak C-H⋯O hydrogen bonds, likely associated with a strong dipole moment present in the mol-ecule, dictate the arrangement of mol-ecules in the crystal structure.
متن کامل9-(Pent-4-enyl)anthracene
In the title compound, C(19)H(18), the anthracene system is almost planar, with a maximum deviation of -0.039 (1) Å. The structure is stabilized by C-H⋯π inter-actions. The pentene moiety is not planar and is twisted away from the attached anthracene system with a maximum torsion angle of 91.2 (1)°.
