Abstract

Hg(II) coordination complexes containing the tridentate N-(2-methoxyphenyl)-1-(pyridin-2-yl)methanimine ligand were synthesized by using template synthesis approach and characterized using spectroscopic techniques and single crystal X-ray crystallography. The molecular structure and supramolecular features of these compounds were investigated using geometrical, Hirshfeld surface analyses, and theoretical calculations. The supramolecular architecture of these coordination complexes is governed by a combination of π–π, C–H⋯π, and C–H⋯X–M hydrogen bonding interactions. This study may provide further insight into the understanding of the coordination chemistry of Hg(II) containing multidentate Schiff-base ligand and the role of weak non-covalent interactions in the solid-state structure of coordination compounds.

含三齿NNO席夫碱配体的Hg（II）配位化合物：合成，表征和晶体结构分析

摘要

通过模板合成法合成了含有三齿N-（2-甲氧基苯基）-1-（吡啶-2-基）甲亚胺配体的Hg（II）配位配合物，并利用光谱技术和单晶X射线晶体学对其进行了表征。使用几何，Hirshfeld表面分析和理论计算研究了这些化合物的分子结构和超分子特征。这些配位配合物的超分子结构受π–π，C–H⋯π和C–H⋯X–M氢键相互作用的组合控制。这项研究可能会提供进一步的见解，以了解含多齿席夫碱配体的Hg（II）的配位化学以及弱非共价相互作用在配位化合物固态结构中的作用。
