Effects of substituents on the thermodynamic and kinetic stabilities of HCGeX (X = H, CH3, F, and Cl) isomers. A theoretical study

The effect of substitution on the potential energy surfaces of HC equivalen t to GeX (X = H, CH3, F, and Cl) were explored using density functional the ory (B3LYP) and QCISD methods. The theoretical findings suggest that (H)(X) C=Ge: is the minimum on the singlet potential energy surface, regardless of the substituents (X) used. On the other hand, HC equivalent to GeX and XC equivalent to GeH are found to be local minima on the surface, but they are neither kinetically nor thermodynamically stable.
