A 1:2 cocrystal of genistein with isonicotinamide: crystal structure and Hirshfeld surface analysis

Genistein, a naturally occurring polyphenolic compound, was combined with isonicotinamide, a pharmaceutically acceptable coformer, to yield a 1:2 cocrystal [systematic name: 5,7-dihydroxy-3-(4-hydroxyphenyl)chromen-4-one-pyridine-4-carboxamide (1/2)], C15H10O5 center dot 2C(6)H(6)N(2)O. The molecules in the cocrystalline phase are present in their neutral forms, and assemble a molecular layer by means of hydrogen bonding.
