Abstract The goal of this research was to study the electrochemical behavior of tri-nuclear clusters of molybdenum and tungsten - first in the ionic liquid EMIBF4, and then in the polar-aprotic solvent DMSO. Four tri-nuclear cluster compounds were studied: Hexa-μ2-acetatotriaquadi-μ3-oxotrimolybdenum (IV, IV, IV) trifluoromethanesulfonate [Mo₃O₂(O₂CCH₃)₆(H₂O)₃](CF₃SO₃)₂, Hexa-μ2-acetatotriaquadi-μ3-oxodimolybdenum (IV, IV) tungsten (IV) trifluoromethanesulfonate [Mo₂WO₂(O₂CCH₃)₆(H₂O)₃](CF₃SO₃)₂, Hexa-μ2-acetatotriaquadi-μ3-oxomolybdenum (IV) ditungsten (IV, IV) trifluoromethanesulfonate [MoW₂O₂(O₂CCH₃)₆(H₂O)₃](CF₃SO₃)₂, and Hexa-μ2-acetatotriaquadi-μ3-oxotritungsten (IV, IV, IV) trifluoromethanesulfonate [W₃O₂(O₂CCH₃)₆(H₂O)₃](CF₃SO₃)₂. All information gathered from CV data on tri-nuclear clusters will be discussed. The study of the electrodeposition efforts with molybdenum- and tungsten-based tri-nuclear clusters onto Pt electrodes in EMIBF4, and DMSO, will be compared to past investigations by Katovic et al. In addition, the electrochemical properties of these four trinuclear clusters in the DMSO-based solvent system were explored and are novel findings.

铂工作电极上非完整三核团簇电沉积的电化学研究

摘要 本研究的目的是研究钼和钨的三核簇的电化学行为 - 首先在离子液体 EMIBF4 中，然后在极性非质子溶剂 DMSO 中。研究了四种三核簇化合物：Hexa-μ2-acetatotriquadi-μ3-oxotrimolybdenum (IV, IV, IV) 三氟甲磺酸盐 [Mo₃O₂(O₂CCH₃)₆(H₂O)₃](CF₃SO₃)2, Hexa-μ2-quatato-μ2-氧代二钼 (IV, IV) 三氟甲磺酸钨 (IV) [Mo₂WO₂(O₂CCH₃)₆(H₂O)₃](CF₃SO₃)₂, Hexa-μ2-acetatotriquadi-μ3-oxomolybdenum (IV) ditungstenfluoromethanesulfonate [Mo₂WO₂(O₂CCH₃)₆(H₂O)₃] )₆(H₂O)₃](CF₃SO₃)₂，和六-μ2-乙酰三四四-μ3-氧三钨(IV, IV, IV)三氟甲磺酸盐[W₃O₂(O₂CCH₃)₆₂(H₂O)₃](CF₃)。将讨论从三核集群的 CV 数据中收集的所有信息。将钼基和钨基三核簇电沉积到 EMIBF4 和 DMSO 中的 Pt 电极上的研究将与 Katovic 等人过去的研究进行比较。此外，探索了基于 DMSO 的溶剂系统中这四个三核簇的电化学性质，这些都是新发现。
