摘要

The synthesis and X-ray crystal structures of the diborane(4) isomers 1,1-B_2{1,2-(NH)_2C_6H_4}_2 and1,2-B_2{1,2-(NH)_2C_6H_4}_2are described together with the results of quantum chemical calculationswhich shed light on their relative stabilities and degree of aromaticity. Spectroscopic data are alsoprovided for both isomers of the 4-methyl aryl derivative. The compound 1,1-B_2{1-0-2-(NH)C_6H_4}_2has also been prepared and structurally characterised but no evidence was obtained for thecorresponding 1,2-isomer. The compound 1,1-B_2{1,2-(NH)_2C_6H_4}_2 forms a co-crystal with TCNQ, thestructure of which is also reported.
