Chalcones or 1,3-diaryl-2-propen-1-ones belong to the flavonoid family. <...> A vast number of naturally occurring chalcones are polyhydroxylated in the aryl rings. <...> The radical quenching properties of the phenolic groups present in many chalcones have raised interest in using the compounds or chalcone-rich plant extracts as drugs or food preservatives. <...> Chalcones are also finding application as organic compounds reported to have NLO properties; chalcone derivatives are a recognized material because of their excellent blue light transmittance and good crystallization ability. <...> The basic skeleton of chalcones is useful as the starting material for the synthesis of various biodynamic heterocyclic compounds such as cyclohexane derivatives and pyrazoline derivatives [ 7 ]. <...> Owing to the importance of these flavonoid analogs, we report here the crystal structure of the title chalcone derivative. <...> The pyridine ring system and the benzene ring are oriented at a dihedral angle of 83.42(10)ē. <...> The ethyl group is equatorially substituted to the pyridine ring. <...> G. Vasuki thanks the Sophisticated Analytical Instrument Facility, IIT Madras, Chennai, for the X-ray data collection. <...> A co-crystal is obtained in a methanolic solution from methyl 2-(3-chloro-4-methyl-2-oxo-2H-chromen-7-yloxy)acetate and 2-(2-aminophenyl)benzothiazole. <...>
