Crystal structure and Hirshfeld surface analysis of aqua­(1H-imidazole-κN3)[N-(2-oxido­benzyl­idene)threonato-κ3O,N,O′]zinc(II)

Abstract

The crystal structure of the amino acid Schiff base zinc(II) complex synthesized from salicyl­aldehyde, l-threonine and zinc(II) acetate is reported.

The title complex, [Zn(C₁₁H₁₁NO₄)(C₃H₄N₂)(H₂O)], which includes a tridentate ligand, was synthesized from l-threonine and salicyl­aldehyde. One water mol­ecule and one imidazole mol­ecule additionally coordinate the zinc(II) center in a distorted trigonal–bipyramidal geometry. The crystal structure features N—H⋯O and O—H⋯O hydrogen bonds. A Hirshfeld surface analysis indicates that the most important contributions to the packing are from H⋯H/H⋯H (50.7%) and O⋯H/H⋯O (25.0%) contacts.
