Biography
Professor Sevov received his B.S. and M.S. in chemistry in 1983 and 1985, respectively, from the University of Sofia, Bulgaria. In 1993, he obtained his Ph.D. from Iowa State University for research on synthesis and characterization of indium clusters in the solid state. After two years as a postdoctoral fellow at the University of Chicago, he joined the faculty at Notre Dame in 1995. Professor Sevov is a recipient of the Camille and Henry Dreyfus New Faculty Award for 1995, and the Exxon Faculty Fellowship in Solid State Chemistry for 1999.

Research Interests
Chemistry of Main-Group Metals in Negative Oxidation States
This interest has grown out of synthetic work of a new class of clusters and clathrate-like frameworks of group 14. Unprecedented naked clusters of Si94-, Ge94-, and Pb94- (monocapped square antiprisms or tricapped trigonal prisms), Sn86- (square antiprisms), Ge1212- (truncated tetrahedron), and even larger clusters of this group were found recently in the solid-state. Discovered were also many novel anionic species of group 15 such as the multiply-bonded Bi22- and Sb44- as well as mixed main-group - transition-metal anions of the type [As2Nb(µ-As)2NbAs2]n- where the two Nb-atoms are either NbV or of mixed-valence NbIV/NbV. These are only few examples of the potentially rich field of intermetallic Zintl compounds. Our goal is to synthetically explore these systems, investigate crystal and electronic structures of the compounds, and study their physical properties. Furthermore, of great interest is the possibility to bring such anionic clusters and molecules into solution, and to explore their redox chemistry and reactivity. For example, we have oxidatively coupled nine-atom germanium clusters to dimers and trimers, [Ge9-Ge9]6- and [Ge9=Ge9=Ge9]6-, respectively, have derivatized them by various substituents, [Ph2Sb-Ge9-SbPh2]2- and [Ph-Ge9-SbPh2]2-, and have made mixed main-group - transition-metal clusters, [Bi3Mo2(CO)6]3-.
Hydrothermal Exploratory Synthesis of Hybrid Organic-Inorganic Materials with Framework Structures
We are interested in compounds with open-framework structures as well as compounds that contain large multiatomic molecular anions built of transition-metal, borate, and phosphate or phosphonate groups. We have synthesized the first such open-framework borophosphate, CoB2P3O12(OH)•en where ethylenediamine (en) is the organic template, and the first borophosphate templated by a transition-metal complex, [Co(en)3][B2P3O11(OH)2]. Also, we recently synthesized the first large borophosphate polyoxometalate, [MoV5MoVI7O30(BPO4)2(PO4)3(HPO4)3]8- and its phenyl-functionalized version [MoV5MoVI7O30(BPO4)2(Ph-PO4)6]5-. Other systems of interest include extended frameworks made of transition-metal centers connected by organic linkers with two or more functional groups such as di-phosphonates, carboxylate-phosphonates, boronate-phosphonates, carboxylate-boronates, etc.
