Zn^II and Fe^II chloride complexes of a di(methylthiazolidinyl)pyridine ligand were deprotonated to form the corresponding thiolate complexes supported by redox-active iminopyridine moieties. The thiolate donor groups are nucleophilic and reactive toward oxidants, electrophiles, and protons, while the pendant thiazolidine rings are available for hydrogen bonding. Anion exchange with the weakly-coordinating triflate anion resulted in self-assembly of the iminopyridine complexes to form a trimeric [M₃S₃] cluster. Hydrogen bonding closely associates anions with this trimetallic core.

非无辜噻唑烷基硫醇盐配体金属配合物的簇自组装和阴离子结合

二（甲基噻唑烷基）吡啶配体的Zn ^II和 Fe ^II氯化物配合物被去质子化以形成由氧化还原活性亚氨基吡啶部分支持的相应硫醇盐配合物。硫醇供体基团是亲核的，对氧化剂、亲电子试剂和质子具有反应性，而噻唑烷侧链可用于氢键合。与弱配位三氟甲磺酸盐阴离子交换阴离子导致亚氨基吡啶配合物自组装形成三聚体[M ₃ S ₃ ] 簇。氢键将阴离子与该三金属核紧密结合。
