The Inorganic, Bioinorganic and Organometallic Chemistry Program supports the research efforts of Professor H. V. Rasika Dias of the University of Texas at Arlington to obtain and study thermally-stable gold and mercury complexes of carbon monoxide, ethylene, acetylene, and other small alkenes and alkynes. Novel, metal-catalyzed, carbon-halogen bond activation processes are also under investigation. Complexes with mercury(II) and gold(I) bonds to small carbon-based, unsaturated molecules are difficult to isolate. Professor Dias uses certain weakly coordinating anions as supporting ligands or counter anions for the stabilization of such species. The crystalline solids of these complexes display unusually high thermal and air stability. They serve as useful catalysts for various transformations, including carbon-halogen bond activation chemistry. Professor Dias and his group are involved in developing web-based methods for the exchange and dissemination of research results and for the live-delivery of online courses on various aspects of chemistry. The lecture materials are especially intended for students in foreign academic institutions with faculty shortages. Professor Dias is active in mentoring K-12 teachers, high school students, and undergraduate researchers with diverse backgrounds.

无机、生物无机和有机金属化学项目支持德克萨斯大学阿灵顿分校 H. V. Rasika Dias 教授的研究工作，以获取和研究一氧化碳、乙烯、乙炔和其他小烯烃和炔烃的热稳定金和汞络合物。新颖的金属催化碳-卤键活化工艺也在研究中。汞 (II) 和金 (I) 与小碳基不饱和分子键合的络合物很难分离。 Dias 教授使用某些弱配位阴离子作为支持配体或抗衡阴离子来稳定此类物质。 这些配合物的结晶固体表现出异常高的热稳定性和空气稳定性。 它们可作为各种转化的有用催化剂，包括碳-卤键活化化学。 迪亚斯教授和他的团队致力于开发基于网络的方法，用于交换和传播研究成果以及实时提供化学各个方面的在线课程。 讲座材料特别适合师资短缺的国外学术机构的学生。 Dias 教授积极指导具有不同背景的 K-12 教师、高中生和本科生研究人员。
