A series of mercapto-oxo containing reagents [3-mercap-topropionic acid (H2-3MPA), 4-mercaptophenol (H2-4MP), 2-mercaptopyridine N-oxide (H-2MPO)] was treated with di-ethylzinc (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 tetranu-clear species consisting of two Zn(Et)(py) moieties bridged by the oxygens of two 4MP ligands with the thiolate sites of each terminated by Zn(Et)(py)2 moieties. Compound 3 adopts a monomeric species using a chelating 2MPO, a terminal Et, and a bound py to fill the Td coordination of the Zn metal center. Compounds 1-3 were then used to generate nanoparticles via solution precipitation and solvothermal routes to determine the effect these precursors have on the morphology and composition of the final materials produced. Compounds 1-3 were found to form zincite, zinc metal, or mixed zincite/wurtzite phases from solution precipitation or solvothermal routes; however, no routes yielded the mixed anion (i.e., ZnOxSy) materials. © Wiley-VCH Verlag GmbH & Co.
