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，生物无机和有机化学计划支持教授H。V. Rasika Dias的德克萨斯大学在阿灵顿获得和研究热稳定的金和汞的一氧化碳，乙烯，乙炔，和其他小烯烃和炔烃的配合物。新型的金属催化的碳-卤键活化方法也在研究之中。汞（II）和金（I）键合到小的碳基不饱和分子上的络合物很难分离。 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这些物质。 这些配合物的结晶固体显示出异常高的热稳定性和空气稳定性。 它们作为各种转化的有用催化剂，包括碳-卤素键活化化学。 Dias教授和他的小组参与开发基于网络的方法，以交流和传播研究成果，并实时提供化学各方面的在线课程。 讲座材料是特别为教师短缺的外国学术机构的学生准备的。 Dias教授积极指导K-12教师，高中生和具有不同背景的本科研究人员。
