Abstract
In four N-(4-halophenyl)-4-oxo-4H-chromene-3-carboxamides, halo = -F, -Cl, -Br and -I, the molecules are essentially planar and exhibit anti conformations with respect to the C—N rotamer of the amide and with cis geometries with respect to the relative positions of the C3arom—C2arom bond of the chromone ring and the carbonyl group of the amide.
