Source of material

A mixture of berberine chloride (370 mg, 1 mmol), and vanillic acid (168 mg, 1 mmol) was dissolved in 25 mL ethanol. The resulting solution was kept in air to give rise to yellow block crystals.

Experimental details

H atoms on C atoms were located geometrically (C—H = 0.95 or 0.99 Å) with Uiso(H) = 1.2 or 1.5 Ueq(C). H atoms bonded to O were located by difference maps and refined with the Uiso(H) = 1.2 Ueq(O).

Discussion

During cocrystallization experiments, cocrystal hydrates could be often unexpectedly obtained in which water molecules play important roles in the structures [4, 5] . Berberine is a natural alkaloid extracted from Huanglian (Rhizoma Coptidis), which is commonly marketed as hydrochloride salt [6]. It exhibits new applications in the treatment of diabetes, hyperlipidemia and cancer [7]. The crystal structure of its tetrahydrate was studied in detail [8]. The chloride salt could undergo solid state transformations among anhydrate, dehydrate and tetrahydrate [9]. Until now, cocrystallization based on berberine chloride has not been exploited. In this paper, vanillic acid as cocrystal former cocrystallized with berberine chloride in ethanol to give rise to a cocrystal hydrate in which there exist specific hydrogen-bonding interactions between vanillic acid and water molecules.

Cocrystallization of berberine chloride and vanillic acid gave rise to the title compound. The asymmetric unit contains one berberine chloride, half of vanillic acid and two and half of water molecules. Three water molecules and vanillic acid are coplanar in the mirror plane. The chloride anion is simultaneously hydrogen-bonded to three different water molecules. Two chloride and two water molecules form a synthon R42(8) connected to the other three water molecules. As a result, five water molecules and two chloride anions interact through various hydrogen-bonding interactions to form a symmetrical cluster unit [Cl2⋅5H2O] (cf. the figure). The hydrogen-bonding interactions between water and berberine generated a subunit, [C20H18NO4Cl]2⋅5H2O. The carboxylic group of vanillic acid is hydrogen-bonded to one water molecule to form a symmetrical pentahydrate in which vanillic acid and three water molecules are located in a mirror plane. The hydroxyl of vanillic acid resulted in hydrogen-bonding interactions with water molecule from adjacent pentahydrate, which gave rise to a hydrogen-bonded chain.
