Equilibrium Structures and Isomerization Reactions of the Unsaturated Germylenoid H2C=GeLiF

The unsaturated germylenoid H2C=GeLiF has been studied by using DFT method at the B3LYP/6-311 G (d, p) level. Geometry optimization calculations indicate that H2C=GeLiF has three equilibrium configurations, in which the p-complex is the lowest in energy and the most stable structure. Two transition states for isomerization reactions of H2C=GeLiF are located and the energy barriers are calculated. For the most stable one, vibrational frequencies and infrared intensities have been predicted.
