Soluble Metal Selenides and Tellurides

西北大学的伊贝斯教授将在无机化学、生物无机化学和金属有机化学项目的支持下，研究可溶金属硫化物的合成。这些物种属于(MxQy)z型，其中M是金属，Q是硒或碲。所采用的合成技术多种多样，但它们将主要集中在金属化合物与多硒或多碲化物在非水溶剂中的反应或取代反应。产物的表征将通过~(77)Se和~(125)Te核磁共振谱以及单晶的X射线衍射研究来进行。氧和硫的可溶简单金属化合物是广为人知的。人们对元素周期表中较低的元素硒和碲的类似化合物知之甚少。获得这种知识的第一步是化合物的制备。初步研究表明，其中一些化合物将与相应的硫化物具有很强的相似性，但其他化合物将代表全新的结构类型。因此，将在一个多管齐下的研究计划中使用广泛的合成方法，旨在揭示从这些元素中可以制备的化合物的种类。

Professor Ibers of Northwestern University will investigate the synthesis of soluble metal chalcogenide compounds with support from the Inorganic, Bioinorganic, and Organometallic chemistry Program. These species are of the type (MxQy)z- where M is a metal and Q is selenium or tellurium. The synthetic techniques to be employed are varied, but they will center mainly on reactions of metal compounds with polyselenide or polytelluride species in non-aqueous solvents or on replacement reactions. Characterization of the resultant products will be by 77Se and 125Te NMR spectroscopy and by X-ray diffraction studies of single crystals. %%% Simple metal compounds of oxygen and of sulfur that are soluble are widely known. Much less is known about similar compounds of those elements lower in the periodic table, selenium and tellurium. The first step in gaining such knowledge is the preparation of the compounds. Initial studies suggest that some of these compounds will bear strong similarities to the corresponding sulfides, but others will represent totally new structural types. Thus, a broad range of synthetic methods will used in a multi-pronged research program directed towards uncovering the variety of compounds that con be prepared from these elements.
