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.

and the silver(I) complex [Ag(E)-3}2][SbF6] have been prepared and characterized, including a single crystal X-ray determination of the latter. Surprisingly, no π-stacking between anthracene or pyridine domains is observed in the solid state, and the crystal packing is dominated by Ag⋯F, CHanthracene⋯π-pyridine and CH⋯F interactions. In contrast to (E)-2 and [Ag(E)-2}2]+, neither (E)-3 nor [Ag(E)-3}2]+

brine shrimp lethality assay, and were able to bind to quadruplex DNA. On the other hand, the pyca- and acpy-ligated compounds did not display any lethality and were unable to interact with DNA. The results indicate that the inclusion of a chalcone ligand plays an important role in improving the cytotoxicity and DNA binding capabilities of molybdenum carbonyl compounds.
