title: Bis{N,N,N-trimethyl-2-oxo-2-[2-(2,3,4- trihydroxy-benzyl-idene)hydrazin-yl]ethanaminium} tetra-chlorido-zincate(II) methanol solvate.
abstract: The asymmetric unit of the title compound, (C(12)H(18)N(3)O(4))(2)[ZnCl(4)]·CH(3)OH, consists of two Girard reagent-based cations, a tetra-chlorido-zincate anion and a mol-ecule of methanol as solvate. These components are inter-connected 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 inter-molecular inter-action is realized between the cation and anion [H⋯Cl = 2.29 (5) Å; O-H⋯Cl = 167 (3)°]. C-H⋯O inter-actions also play a important role in the inter-connection of the cations.
