AAAS
Chair-Elect, Chair, and Retiring Chair, Section on Chemistry
The Section Chair serves a three-year term -- the first year as Chair-Elect, the second year as Chair, and the third year as Retiring Chair. During all three years, he or she serves as a member of the Section Committee of his or her section and of the Section Committee's Steering Group.
In addition to specific duties in connection with the Annual Meetings, the Chair-Elect, Chair, and Retiring Chair should take active roles in cooperation with the Section Secretary in (a) identifying opportunities for the active involvement of affiliated organizations in the affairs of the section, including lively symposia at Annual Meetings; (b) identifying broad issues in science of interest to the section and to the association overall; and (c) commenting to the Chief Executive Officer, the Board Chair, or the Chair of the Committee on Council Affairs on the operations and priorities of the Association, including worthwhile new initiatives deserving consideration in future planning.Worcester Polytechnic Institute

Density Functional Theory and Low-Temperature Matrix Investigations of CO-Loss Photochemistry from [(C5R5)Ru(CO)2]2 (R=H, Me) Complexes
Journal of Cluster Science, Vol. 15, No. 5, pp. 469-487
The photochemical CO-loss products of the diruthenium complexes [CpRu(CO)2 ]2 (5; Cp = g5 -C5 H5 ), [Cp*Ru(CO)2 ]2 (5*; Cp* = g5 -C5 (CH3 )5 ) and CpCp*[Ru(CO)2 ]2 (50 ) have been studied experimentally in low-tempera- ture (96 K) matrices in 3-methylpentane by using IR spectroscopy. It is pro- posed that all three complexes undergo single-CO-loss chemistry but that the products have different structures. The single-CO-loss product from 5 is pro- posed to have one bridging and two terminal carbonyl ligands, whereas 5* and 50 generate triply bridged CO-loss products similar to that observed from [CpFe(CO)2 ]2 and [Cp*Fe(CO)2 ]2 . Double-CO-loss from 5* and 5’ is also apparently observed. Relativistic DFT calculations have been carried out on various isomers of the starting materials and on potential CO-loss products from 5. The calculations suggest that the triply bridged product Cp2Ru2 (l-CO)3 (6) might have a singlet ground state in contrast to the corresponding diiron complex Cp2Fe2(l-CO)3 (3), which has a triplet ground state.

Metal-metal bonding in the actinide elements: Conceptual synthesis of a pure two-electron U-U fδ single bond in a constrained geometry of U2(OH)10
Inorganica Chimica Acta
By utilizing high symmetry and geometric constraints, it is proposed that a mol. with a pure U-U 5fδ bond can be constructed. The proposed mol. is D4h U2(OH)10 with the following geometric constraints: (1) All of the U-O-H linkages are linear, assuring that each linear hydroxide group has two filled π orbitals capable of donating to the U atoms, and (2) all of the U-U-O(eq) bond angles are 90°, which assures that all of the U valence orbitals except for the fδ[zxy] orbital are destabilized by ligand donation. Preliminary DFT calcns. with relativistic effective core potentials indicate that the fσ orbital is not destabilized enough in this simple model, and that it is essentially degenerate with the fδ orbital, likely leading to a triplet (fσ)1(fδ)1 single bond. Single point calcns. were used to est. the U-U bond length and bond strength of the U-U single bond in constrained U2(OH)10 with an (fσ)2(fδ)0 configuration. We est. that the bond length is 3.55 Å and the bond strength is 9.7 kcal/mol for this very fragile mol.
