Abstract

This paper deals with the synthesis, structural studies, and behavior in solution of unprecedented coordination complexes built by the association of a panel of 14 representative thiosemicarbazone ligands with the cluster [MoOS]. These complexes have been thoroughly characterized both in the solid state and in solution by XRD and by NMR, respectively. In particular, HMBC H{N} and H DOSY NMR experiments bring important elements for understanding the complexes' behavior in solution. These studies demonstrate that playing on the nature and the position of various substituents on the ligands strongly influences the coordination modes of the ligands as well as the numbers of isomers in solution, mainly 2 products for the majority of complexes and up to 5 for some of them.

摘要

本文涉及由14种代表性硫代卡巴腙配体与簇合物[MoOS]缔合构建的前所未有的配位络合物的合成、结构研究及其在溶液中的行为。这些络合物分别通过XRD和NMR在固态和溶液中进行了全面表征。特别是，HMBC H{N}和H DOSY NMR实验为理解络合物在溶液中的行为提供了重要信息。这些研究表明，改变配体上各种取代基的性质和位置会强烈影响配体的配位模式以及溶液中异构体的数量，大多数络合物主要有2种产物，有些络合物则多达5种。
