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.

无机化学、生物无机化学和金属有机化学计划支持埃默里大学的克雷格·L·希尔教授的努力，以制备和表征新型的多金属氧酸盐(POM)络合物，这些络合物要么含有末端的Ru-氮键，要么含有末端具有金属-氧键的后过渡金属。这些络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多金属氧酸盐。与大多数催化反应一样，在较温和的条件下(空气氧化、水相容)和较快的速度可以更有选择性地获得新产品。这项工作的最后一个方面包括研究无机簇合物中的离子配对和输运，这些簇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上的黑人学院和大学(HBCU)的合作，主要是本科生机构和国际组织(在德国和法国)。他是NSF无机研讨会以及北约复杂性高级研究研讨会的现任联合主席。
