9407284 Reed U of Southern California Dr. Christopher Reed, Chemistry Department, University of Southern California, is supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program for the study of weakly coordinating anions. In this study, Reed will prepare a variety of new anions which contain no good coordination sites and in which the charge is delocalized over a large volume. These will be used as counter ions both to obtain low-coordinate cations and to stabilize complexes of very weak donors such as xenon, hydrocarbons, etc. Using the of non-coordinating anions the magnetic properties of admixed-intermediate spin state Fe(III) complexes will be investigated order to establish the relative ligand field strengths of these anions. In general, negatively charged chemical species (anions) tightly associate with species bearing a positive charge (cations). This project will focus on the preparation of anions whose shape and charge distribution prevents them from closely approaching a cation. This will result in highly reactive cations, whose properties will be evaluated. While there are implications to several areas of chemistry, one of the most important is in the design of new catalysts for several industrially important processes.

9407284 南加州里德大学 Christopher Reed 博士，南加州大学化学系，受到无机、生物无机和有机金属化学项目的支持，用于弱配位阴离子的研究。在这项研究中，里德将制备多种新的阴离子，这些阴离子不包含良好的配位位点，并且其中电荷在大体积上离域。这些将用作抗衡离子，以获得低配位阳离子并稳定非常弱的供体（例如氙、碳氢化合物等）的配合物。使用非配位阴离子，将研究混合中间自旋态 Fe(III) 配合物的磁性，以便建立这些阴离子的相对配体场强度。 一般来说，带负电荷的化学物质（阴离子）与带正电荷的物质（阳离子）紧密结合。该项目将重点关注其形状和电荷分布阻止其紧密接近阳离子的阴离子的制备。这将产生高活性阳离子，其特性将被评估。虽然这对化学的多个领域都有影响，但最重要的影响之一是为几个工业上重要的过程设计新催化剂。
