(Z)-3-(Anthracen-9-yl)-1-(2-ethoxyphenyl)prop-2-en-1-one1
The mol-ecule of the title chalcone, C(25)H(20)O(2), consisting of 2-eth-oxy-phenyl and anthracene rings bridged by a prop-2-en-1-one unit, is twisted and exists in the Z configuration with respect to the central C=C bond. The dihedral angle between the benzene and anthracene rings is 78.17 (9)°. The propene unit makes dihedral angles of 44.5 (2) and 81.1 (2)° with the benzene and anthracene ri...
متن کامل(E)-3-(Anthracen-9-yl)-1-(2-bromophenyl)prop-2-en-1-one
The mol-ecule of the title chalcone, C(23)H(15)BrO, is not planar and exists in the E configuration with respect to the central C=C bond. The dihedral angle between the benzene and anthracene rings is 83.58 (6)°. The prop-2-en-1-one bridge makes dihedral angles of 63.00 (7) and 42.62 (16)° with the benzene and anthracene rings, respectively. In the crystal, mol-ecules are linked into dimers by ...
متن کامل(E)-3-(Anthracen-9-yl)-1-(furan-2-yl)prop-2-en-1-one1
In the mol-ecule of the title heteroaryl chalcone derivative, C(21)H(14)O(2), the almost planar prop-2-en-1-one unit [r.m.s. deviation = 0.0087 (1) Å] forms dihedral angles of 5.81 (7) and 49.85 (6)°, respectively, with the furan ring and anthracene ring system. In the crystal structure, the mol-ecules are linked into a two-dimensional network parallel to (100) by C-H⋯O hydrogen bonds and π⋯π i...
متن کامل(2E)-3-(2-Anthracen-2-yl)-1-(2-hydroxyphenyl)prop-2-en-1-one
The asymmetric unit of the title compound, C(23)H(16)O(2), contains two independent mol-ecules in which the dihedral angles between the anthracene ring system and the benzene ring are 73.0 (3) and 73.3 (3)°. In both independent mol-ecules, the hy-droxy group is involved in an intra-molecular O-H⋯O hydrogen bond. The crystal packing is stabilized by π-π inter-actions [centroid-centroid distances...
متن کاملRedetermination of (E)-3-(anthracen-9-yl)-1-(2-hydroxyphenyl)prop-2-en-1-one1
The redetermined structure of title chalcone derivative, C(23)H(16)O(2), corrects errors in the title, scheme and synthesis in the previous report of the same structure [Jasinski et al. (2011 ▶). Acta Cryst. E67, o795]. There are two independent mol-ecules in the asymmetric unit with slight differences in bond lengths and angles. The dihedral angle between the benzene ring and the anthracene ri...
