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.

西北大学的伊伯斯教授将研究 用载体合成可溶性金属硫属化合物 无机、生物无机和有机化学 程序. 这些物质是（MxQy）z-型的，其中M是 并且Q是硒或碲。 合成技术 就业是多种多样的，但他们将主要集中在 金属化合物与多硒化物或多碲化物的反应 在非水溶剂或置换反应中的物种。 所得产物的表征将通过77 Se和 ~（125）Te核磁共振谱和X射线衍射研究 单晶体 %%% 可溶的氧和硫的简单金属化合物 是众所周知的。 对类似化合物的了解要少得多 在周期表中较低的元素中，硒和 碲。 获得这些知识的第一步是 化合物的制备。 初步研究表明， 这些化合物中的一些将与 其他的则代表全新的 结构类型 因此，广泛的合成方法 将用于一个多方面的研究计划， 揭示了可以由以下物质制备的各种化合物： 这些元素。
