Synthesis and Novel Crystal Structure Analysis of Anthracene-Based Chalcone Derivatives
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 P2(1)/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 P2(1)/n space group. Anthracenyl chalcone 4 crystallizes in the centrosymmetric triclinic P-1 space group.
