Synthesis, crystal structure and Hirshfeld surface analysis of 2-oxo- <i>N</i> -(pyridin-4-yl)-2 <i>H</i> -chromene-3-carboxamide

(16) synthons that propagate along the [010] direction. The mol-ecular packing in the crystal is further consolidated by C= O⋯π inter-actions and π-π stacking with centroid-centroid separations of 3.732 (2), 3.815 (2) and 3.947 (2) Å. The two-dimensional fingerprint plots indicate that the major contributions to the crystal packing arise from H⋯O/O⋯H (19.5%), H⋯C/C⋯H (14.1%), H⋯N/N⋯H (8.0%) and O⋯C/C⋯O (5.0%) inter-actions.
