摘要

报道了水杨醛、l-苏氨酸和醋酸锌合成的氨基酸席夫碱锌（II）配合物的晶体结构。以l-苏氨酸和水杨醛为原料合成了含有三齿配体的标题配合物[Zn(C11H11NO4)(C3H4N2)(H2O)]。另外，一个水分子和一个咪唑分子在扭曲的三角-双锥体几何结构中使锌（II）中心协调。晶体结构具有N-H⋯O和O - h⋯O氢键。Hirshfeld表面分析表明，对堆积最重要的贡献是H⋯H/H⋯H（50.7%）和O⋯H/H⋯O（25.0%）接触。

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

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.

期刊介绍： Acta Crystallographica Section E: Crystallographic Communications is the IUCr''s open-access structural communications journal. It provides a fast, simple and easily accessible publication mechanism for crystal structure determinations of inorganic, metal-organic and organic compounds. The electronic submission, validation, refereeing and publication facilities of the journal ensure rapid and high-quality publication of fully validated structures. The primary article category is Research Communications; these are peer-reviewed articles describing one or more structure determinations with appropriate discussion of the science.
