Abstract

Abstract: Four novel anthracene-based chalcone derivatives, ( E )-1-(anthracen-9-yl)-3-(4-nitrophenyl)prop-2-en-1-one 1, ( E )-1-(anthracen-9-yl)-3-(3-chlorophenyl)prop-2-en-1-one 2, ( E )-1-(anthracen-9-yl)-3-(3, 4, 5-trimethoxyphenyl)prop-2-en-1-one 3, and ( E )-1-(anthracen-9-yl)-3-(pyridin-4-yl)prop-2-en-1-one four were synthesized and their structures were solved by single crystal X-ray diffraction methods. The anthracenyl chalcone 1 crystallizes in the centrosymmetric monoclinic P 21 / c space group. The crystal structure analysis shows that the molecules of one form two dimensional (2D) corrugated layer structure. The anthracenyl chalcone 2 crystallizes in the centrosymmetric triclinic P -1 space group and forms one dimensional (1D) tape like structure in the crystal. Compound 3 crystallizes in the centrosymmetric monoclinic P 21 / n space group. Anthracenyl chalcone 4 crystallizes in the centrosymmetric triclinic P -1 space group.
