The Inorganic, Bioinorganic, and Organometallic Chemistry Program supports the efforts of Professor Craig L. Hill of Emory University to prepare and characterize new classes of polyoxometalate (POM) complexes containing either terminal ruthenium-nitrido bonds or late transition metals with terminal metal-oxo bonds. The catalytic abilities of these complexes are under investigation. In another project, robust chiral microporous solids are prepared via self-assembly methods and form the first enantiopure polyoxometallates that can undergo asymmetric oxidation catalysis. As with most catalysis reactions, new products may be obtained more selectively, under milder conditions (air oxidation, water-compatible), and at a faster rate. The final aspect of this work includes studies of ion pairing and transport in inorganic cluster compounds which contain structurally well-defined internal water pools. These later studies have relevance to biology, medicine and geology.Professor Hill is actively engaged in collaborations with several Historically Black Colleges and Universities (HBCUs), primarily undergraduate institutions and international groups (in Germany and France). He is the current co-chair of the NSF Inorganic Workshop as well as the NATO Advanced Research Workshop on Complexity.

无机、生物无机和有机金属化学项目支持埃默里大学 Craig L. Hill 教授的工作，以制备和表征新型多金属氧酸盐 (POM) 配合物，该配合物包含末端钌-氮化键或具有末端金属-氧键的后过渡金属。 这些配合物的催化能力正在研究中。 在另一个项目中，通过自组装方法制备了坚固的手性微孔固体，并形成了第一个可以进行不对称氧化催化的对映体纯多金属氧酸盐。 与大多数催化反应一样，可以在更温和的条件（空气氧化、与水兼容）下、以更快的速度更有选择性地获得新产物。这项工作的最后一个方面包括研究无机簇化合物中的离子配对和传输，这些化合物包含结构明确的内部水池。 这些后来的研究与生物学、医学和地质学相关。希尔教授积极参与与几所历史黑人学院和大学 (HBCU) 的合作，主要是本科院校和国际团体（在德国和法国）。 他现任美国国家科学基金会无机研讨会以及北约复杂性高级研究研讨会的联合主席。
