Soluble Transition-Metal Chalcogenides

在无机化学、生物无机化学和金属有机化学计划的支持下，詹姆斯·A·伊贝斯教授将探索硫系化合物中可溶过渡金属化合物的化学，这组元素包括氧、硫、硒和碲。研究这些物种的一个实际原因是它们与用作电子材料的金属硫化物和硒化物有着密切的关系。该项目将侧重于可溶过渡金属硒的化学。将合成和表征四硒代钨酸盐(II)和四硒代钼酸盐(II)的混合金属络合物，以及六硒代钨酸盐(II)等高级共生体的混合金属络合物。将用溶液方法合成新的过渡金属硒与钨或钼以外的金属的络合离子，以及新的烷基硒/硒混合物种。我们还将研究新的过渡金属硫化物离子的固态路线。最后，我们将研究可溶硫化物物种的反应化学，重点是它们与活化的乙炔的反应。

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.
