| dc.description | The gas-phase ion/molecule reactions of F- and EtO- with Ge(OEt)4 yield readily and exclusively pentacoordinated complexes XGe(OEt)4 - (X = F, EtO) at pressures in the 10-8 T range as observed by FT-ICR techniques. These hypervalent species are prone to undergo sequential fragmentations induced by infrared multiphoton excitation that lead to a variety of germyl and germanate anions. In the case of FGe(OEt)4 -, three primary competitive channels are observed in the IRMPD process that can be identified as (EtO) 3GeO-, F(EtO)2GeO- and (EtO) 3Ge-. Ab initio calculations have been carried out to characterize the primary fragmentation paths induced by IRMPD and the most favorable structure of the resulting anions. The gas-phase acidity of a number of these germanium-containing ions have been estimated by bracketing experiments and by theoretical calculations. Germanate anions such as (EtO) 3GeO- undergo some interesting reactions with H 2S to give rise to anions such as (EtO)3GeS- and (EtO)2Ge(OH)S-. © 2010 Elsevier B.V. All rights reserved. | |
