Crystal structure of the mixed methanol and ethanol solvate of bis­{3,4,5-trimeth­oxy-N′-[1-(pyridin-2-yl)ethyl­idene]benzohydrazidato}zinc(II)

The unit cell of the title compound, [Zn(C(17)H(18)N(3)O(4))(2)]·CH(4)O·C(2)H(6)O, contains two complex mol­ecules related by an inversion centre, plus one methanol and one ethanol solvent molecule per complex molecule. In each complex, two deprotonated pyridine aroylhydrazone ligands {3,4,5-trimeth­oxy-N′-[1-(pyridin-2-yl)ethyl­idene]benzohydrazide} coordinate to the Zn(II) ion through the N atoms of the pyridine group and the ketamine, and, additionally, through the O atom of the enolate group. In the crystal, dimers are formed by π–π inter­actions between the planar ligand moieties, which are further connected by C⋯O and C⋯C inter­actions. The inter­molecular inter­actions were investigated using Hirshfeld surface analysis and two-dimensional fingerprint plots, revealing that the most important contributions for the crystal packing are from H⋯H (44.8%), H⋯C/C⋯H (22.2%), H⋯O/O⋯H (18.7%) and C⋯C (3.9%) inter­actions.
