During systematic investigations of the biological action enhancement of well known compounds, a new metal complex, namely, bis-(3,5-di-nitro-benzoato)(ethane-1,2-di-amine)zinc(II), [Zn(CHNO)(CHN)], was synthesized and the structure of its ortho-rhom-bic form has determined. The synthesis and crystal structure of the monoclinic polymorph has previously been reported [Ibragimov (2020 ▸). , 45-50]. The zinc ion has a distorted tetra--hedral environment formed by two monodentate 3,5-di-nitro-benzoato anions and chelating ethyl-enedi-amine mol-ecule. In the crystal, the complex mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds into a two-dimensional network parallel to the plane. The Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H⋯O/O⋯H (43.4%) and O⋯C/C⋯O (17.7%) inter-actions.
在对知名化合物的生物活性增强进行系统研究期间，合成了一种新的金属配合物，即双（3,5 - 二硝基苯甲酸根）（乙烷 - 1,2 - 二胺）锌（II），[Zn(CHNO)(CHN)]，并确定了其正交晶型的结构。单斜晶型多晶型物的合成和晶体结构此前已有报道[伊布拉吉莫夫（2020 ▸）。，45 - 50]。锌离子具有由两个单齿3,5 - 二硝基苯甲酸根阴离子和螯合乙二胺分子形成的扭曲四面体环境。在晶体中，配合物分子通过N - H⋯O和C - H⋯O氢键连接成平行于平面的二维网络。 Hirshfeld表面分析表明，对晶体堆积最重要的贡献来自H⋯O/O⋯H（43.4%）和O⋯C/C⋯O（17.7%）相互作用。
