A 1:1 cocrystal of baicalein with nicotinamide

Cocrystallization of baicalein with nicotinamide yields a 1:1 cocrystal [systematic name: pyridine-3-carboxamide–5,6,7-trihydroxy-2-phenyl-4 H -chromen-4-one (1/1)], C 6 H 6 N 2 O·C 15 H 10 O 5 . The asymmetric unit contains one baicalein and one nicotinamide molecule, both in neutral forms. Molecules in the cocrystal form column motifs stabilized by an array of intermolecular hydrogen bonds.
