Abstract: Single-crystal study of indolyl chalcone (E)-1-(4-bromophenyl)-3-(1-H-indol-3-yl)-prop-2-en-1-one is reported here. It has been synthesized by microwave assisted method from indole-3-carbaldehyde and 4-bromo acetophenone by Claisen-Schmidt reaction. IR,1H NMR and HRMS data is reported here. The crystalline structure of this compound is described within the sp. gr. I -4; its unit cell parameters are a = 23.9636(17)Å,b = 23.9636(17)Å,c = 5.1428(5)Å. Crystallographic study shows formation of hydrogen-bonded cyclic tetramer around a 2-fold axis and 4-fold roto-inversion axis through N1–H1···O1 interactions between the indolic NH group as a hydrogen-bond donor and the carbonyl O atom as a hydrogen-bond acceptor.
