Zernike Institute for Advanced Materials Colloquium Laura Gagliardi


03 februari 2011 FWN-Building 5111.0080, Nijenborgh 4, 9747 AG, Groningen
Speaker: Prof. Dr. Laura Gagliardi
Affiliation: University of Minnesota, Depatment of Chemistry, Minneapolis, USA

Modeling transition metal and actinide chemistry with multiconfigurational quantum chemical methods

Date: Thu Mar 3, 2011
Start: 16.00 (Doors open and coffee available at 15.30)
Location: FWN-Building 5111.0080


Quantum chemistry can be applied to the study of systems containing any atom in the periodic table. In this lecture I will describe our recent studies of polymetallic molecules containing (N)3- and (O)2- ligands, namely [(C5Me5)U(µ-I)2]33-N), [(C5Me5)U(µ-I)2]33-O), and chair and boat conformations of [(C5Me5)2U(µ-N)U(µ-N3)(C5Me5)2]4.[1]These compounds were analyzed to differentiate nitride versus oxide in molecules for which the crystallographic data were unclear, and to provide insight into their electronic structure and unique chemical bonding. The second part of the lecture will be dedicated to the description of recent advances in quantum chemical methods suitable for the study of systems containing metals in general.[2],[3] Examples from transition metal chemistry will be discussed.
