P. Kiprof et Ab. Brown, A G2 level study of monosilabenzene, monogermabenzene and their Dewar benzene and prismane isomers, INTERNET J, 2(23), 1999, pp. 1-11
Silabenzene, Germabenzene, their Dewar-isomers and the respective prismane
structures were studied at the G2 level and the energy differences compared
to the all-carbon compounds. Bond separation energy calculations at the G2
level of theory reveal that the significantly lower energies for silabenze
ne as compared with benzene.
