Soluble Transition-Metal Chalcogenides

在无机、生物无机和 有机化学课程，教授詹姆斯A。伊伯斯将 探索可溶性过渡金属化合物的化学 硫族化物，包括 氧硫硒碲。一个实际的理由， 研究这些物种是因为它们与金属的密切关系 用作电子材料的硫化物和硒化物。 该项目将强调可溶性过渡的化学 金属硒化物。四硒基的混合金属配合物 钨酸盐（II）和四硒钼酸盐（II），以及 较高的同源物，如六硒代二钨酸盐（II）， 合成并表征。将使用解决方法 合成新的过渡金属硒化物配离子， 钨或钼以外的金属，以及新的混合 硒化烷基酯/硒化物种类。固态路由到新 还将研究过渡金属硫属化物离子。 最后，可溶性硫族化物的反应化学 物种将被研究，最初的重点是他们的 与活化的乙炔反应。

With support from the Inorganic, Bioinorganic and Organometallic Chemistry Program, Professor James A. Ibers will explore the chemistry of soluble transition metal compounds of the chalcogenides, that group of elements which includes oxygen, sulfur, selenium and tellurium. A practical reason for studying these species is their close relationship to metal sulfides and selenides which are used as electronic materials. The project will emphasize the chemistry of soluble transition metal selenides. Mixed-metal complexes of tetraselenido- tungstate(II) and of tetraselenidomolybdate(II), as well as of the higher cogeners, such as hexaselenidoditungstate(II), will be synthesized and characterized. Solution methods will be used to synthesize new transition metal selenide complex ions with metals other than tungsten or molybdenum, as well as new mixed alkyl selenolate/selenide species. Solid-state routes to new transition metal chalcogenide ions will be investigated also. Finally, the reaction chemistry of the soluble chalcogenide species will be studied, with initial emphasis on their reactions with activated acetylenes.
