The goals of this project in the Inorganic, Bioinorganic and Organometallic Chemistry Program are to synthesize new transition metal-sulfur compounds, and to characterize these new compounds structurally and with respect to the reactivities of the M-S bonds and the coordinated sulfur ligands. The important role of metal sulfur complexes in industrial and enzymatic catalysis is well-recognized. Previous studies have provided reliable and systematic methods for the synthesis of molybdenum complexes containing Mo=S bonds or eta-2-bonded disulfur or tetrasulfur ligands. Analogous methods will be used to synthesize similar sulfur complexes of other early transition metals, such as Zr, Nb and Ta, and the structures and reactivities of the new complexes will be determined. The synthesis, characterization and reactivity studies of heterometallic clusters that contain various M-S functional groups will be carried out in attempts to evaluate the importance of bimetallic cooperative effects in the activation of specific molecules.

无机化学、生物无机化学和金属有机化学项目的目标是合成新的过渡金属-硫化合物，并表征这些新化合物的结构以及M-S键和配位硫配体的反应活性。金属硫络合物在工业催化和酶催化中的重要作用是公认的。以往的研究已经为合成含Mo=S键或eta-2键的二硫或四硫配体的钼配合物提供了可靠和系统的方法。类似的方法将被用来合成其他早期过渡金属的类似的硫络合物，如Zr，Nb和Ta，并将确定新的络合物的结构和反应活性。我们将对含有不同M-S官能团的异金属簇合物的合成、表征和反应性进行研究，以评价双金属协同效应在特定分子活化中的重要性。
