Abstract

The coordination complex [Zn(phen)(MBT)₂], which exhibits a distorted tetrahedral geometry, was synthesized. Single-crystal X-ray analysis and Hirshfeld surface analysis revealed the presence of several intermolecular C—H⋯N and C—H⋯π interactions.

The coordination complex [Zn(C₇H₄NS₂)₂(C₁₂H₈N₂)] or [Zn(MBT)₂(phen)], was synthesized using ethanol solutions of Zn(CH₃COO)₂·2H₂O, 1,10-phenanthroline (phen) and 2-mercaptobenzothiazole (MBTH-neutral). Single-crystal X-ray diffraction analysis revealed that the zinc atom resides on a crystallographic twofold axis within the asymmetric unit. In the complex, the zinc atom coordinates two 2-mercaptobenzothiazolate (MBT; anionic form of MBTH) ligands in a monodentate fashion through their sulfur atoms, while phenanthroline acts as a bidentate ligand, chelating the zinc center. Further structural analysis, including Hirshfeld surface and two-dimensional fingerprint plot studies, indicated the presence of multiple intermolecular interactions, particularly C—H⋯N and C—H⋯π interactions, contributing to the cohesion and packing of the crystal structure.

双-（苯并噻唑-2-硫醇-κ s）（1,10-phen-anthroline-κ 2n，N'）锌的合成及晶体结构分析

以Zn(CH3COO)2·2H2O、1,10-菲罗啉（phenen）和2-巯基苯并噻唑（MBTH-neutral）为溶剂合成配合物[Zn(C7H4NS2)2(C12H8N2)]或[Zn(MBT)2(phen)]。单晶x射线衍射分析表明，锌原子位于不对称单元内的双轴上。在配合物中，锌原子配位两个2-巯基苯并噻唑酸盐(MBT；阴离子形式的MBTH)配体以单齿方式通过它们的硫原子，而菲罗啉作为双齿配体，螯合锌中心。进一步的结构分析，包括Hirshfeld表面和二维指纹图研究，表明存在多种分子间相互作用，特别是C-H⋯N和C-H⋯π相互作用，有助于晶体结构的内聚和堆积。
