Hexacomponent (123456) alloy: (a) single crystal, (b) single-crystal structure showing one full molecule of naftopidil (1) and five acids with a site occupancy factor of 0.12 benzoic acid (2), 0.27 2-hydroxybenzoic acid (3), 0.14 2,3-di­hydroxybenzoic acid (4), 0.20 2,4-di­hydroxybenzoic acid (5) and 0.27 2,6-di­hydroxybenzoic acid (6). The binary salts form an [R_2^2](9) synthon which is also present in the hexacomponent (123456) alloy. (c) DSC endotherm, showing a single melting point at 176°C which is different from the melting point of the single components as well as the binary salts. (d) PXRD shows bulk-phase purity experimental PXRD pattern compared with the calculated powder diffraction line pattern from the crystal structure.
