二（甲基噻唑烷基）吡啶配体的ZnII和FeII氯化物配合物被去质子化，形成由氧化还原活性亚氨基吡啶部分支撑的相应硫醇盐配合物。硫醇盐供体基团是亲核的，并且对氧化剂、亲电子试剂和质子具有反应性，而侧基噻唑烷环可用于氢键合。与弱配位的三氟甲磺酸根阴离子的阴离子交换导致亚氨基吡啶络合物自组装形成三聚体[M3S3]簇。氢键使阴离子与这种三金属核紧密结合。
ZnII and FeII 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.
