Synthesis and Characterization of Thiolate-Oxo Ligated Zinc Alkyl Derivatives for Production of Zn-Based Nanoparticles.

ABSTRACT: A series of mercapto-oxo containing reagents [3-mercaptopropionic acid (H₂-3MPA), 4-mercaptophenol (H₂-4MP), 2-mercaptopyridine-N-oxide (H-2MPO)] was reacted with diethyl zinc (ZnEt₂) in hexanes/pyridine (py) to yield {(μ₄-3MPA)[Zn(Et)(py)]₄}_∞ (1), [(py)₂(Et)Zn(μ₃-4MP)Zn(Et)(py)]₂ (2), and (2MPO)Zn(Et)py (3). For polymeric 1, each of the functional sites of the 3MPA was bound to four tetrahedral (Td) coordinated Zn(Et)(py) subunits. The sulfur of the 3MPA bridges two of the 'Zn(Et)(py)' subunits, which are also bridged by the two carboxylate oxygens of another 3MPA to propagate the chain. In contrast, 2 forms a discrete tetranuclear species consisting of two
