Abstract

The asymmetric unit of the title compound, (C12H18N3O4)2[ZnCl4]·CH3OH, consists of two Girard reagent-based cations, a tetrachloridozincate anion and a molecule of methanol as solvate. These components are interconnected in the crystal structure by an extensive network of O—H...O, N—H...O, C—H...O, O—H...N, O—H...Cl, N—H...Cl and C—H...Cl hydrogen bonds. The shortest intermolecular interaction is realized between the cation and anion [H...Cl = 2.29 (5) Å; O—H...Cl = 167 (3)°]. C—H...O interactions also play a important role in the interconnection of the cations.
