Stibinidenes and Bismuthinidenes - A New Class of Ligands for Transition Metals
Provider: Grantová agentura ČR
Programme: Standardní projekty
Implementation period: 01.01.15 - 31.12.17
Workplace:
Fakulta chemicko-technologická - Katedra obecné a anorganické chemie
Investigator: Dostál LiborTeam member: Erben Milan
Description:
The project is focused on the investigation of preparation and structure of entirely unexplored monomeric organoantimony(I) and organobismuth(I) compounds ? stibinidenes and bismuthinidenes. These compounds will be stabilized by the help of N,C,N- or N,C-chelating ligands. Central atoms (Sb, Bi) carry two lone pairs of electrons and represent an unprecedented and promising class of ligands for coordination of transition metals. Thus, the second goal of the project is a detailed investigation of the coordination of transition metal compounds (especially carbonyls) by mentioned stibinidenes and bismuthinidenes. The structure of target compounds will be studied mainly by the help of multinuclear NMR, IR and Raman spectroscopy and in the solid state by X-ray diffraction analysis. A theoretical survey dealing with the structure of these unprecedented compounds constitutes an important part of this project. Particular emphasis in this regard will be given to the description of the bonding interaction between transition metals and antimony(I) and bismuth(I) donor centers.
